Tanmoy Mukhopadhyay

Post-doctoral Research Assistant

I am a postdoctoral researcher at the Engineering Science Department of the University of Oxford. Prior to that, I was a PhD student at Swansea University, UK. My research interest lies in the broad area of Mechanics and Multi-Physics analysis. I am a recipient of Zienkiewicz Scholarship from Swansea University covering full tuition fees at international rate and generous living expenses for pursuing doctoral study. Before moving to the UK for pursuing PhD, I received Junior Research Fellowship from Indian Institute of Technology Roorkee. I was awarded the MHRD Scholarship for completing masters study at the same institute. My present research focus is on advanced composites and metamaterials across different length-scales encompassing different critical issues related to solid mechanics and structures. I am actively involved in publishing my research outcomes in high-quality journals and conferences.

Research interests and experiences:
1. PhD thesis: Mechanics of quasi-periodic lattices and mechanical metamaterials
My PhD thesis is based on multi-scale mechanics of quasi-periodic lattices and metamaterials. The main focus is the development of computationally efficient analytical formulae to analyze the mechanical properties of structurally graded and randomly irregular lattices to identify application-specific material micro-structures. A novel concept of representative unit cell element (RUCE) is developed to analyze such spatially varying microstructures. I have proposed different exploitable dimensions in the research of mechanical materials that could be perceived advantageous in various engineering applications. The major contributions are summarized below:
- Development of closed-form analytical formulae for equivalent in-plane and out-of-plane properties of lattices (auxetic and non-auxetic) with spatial irregularity/ variability (Besides investigating the effect of stochasticity in microstructural properties, we have discovered that controlled microstructural randomness can lead to extreme mechanical properties like negative/ zero Poisson’s ratio)
- Visco-elastic analysis of spatially irregular lattices considering the realistic variation in material properties and structural geometry with statistical co-relations (It is shown that a tunable time-dependent deformation behavior can be established in metamaterials)
- Exploitation of space-filling as a new dimension for modulating the mechanical properties of lattice metamaterials
- Frequency-dependence of the elastic moduli of metamaterials (along with their prospective exploitation in vibrating structures) and the emergence of negative stiffness under dynamic environment
- Free vibration and stability analysis of irregular lattices
- Wave propagation analysis through spatially irregular lattices
2. Postdoctoral research: Deployable structures and metamaterials
This work is based on the concept of origami that offers an exciting possibility for the development of new metamaterials, wherein the mechanical properties can be programed according to application-specific needs. Such metamaterials can have attractive applications from the core of sandwich panels and different parts of satellites to biomedical devices in various length-scales. Aim of this project is to develop a physics-based analytical/ numerical approach for analyzing deployable metamaterials. I have started working in this research project from February, 2017 and made significant progress so far in the following major areas:
- Understanding the physics behind deformation of curved creases in deployable metamaterials (curved creases in origami metamaterials can have considerable advantages over the conventional straight creases)
- Development of a self-tunable origami based tubular metamaterial that can show a unique deformation-dependent shape and stiffness modulation characteristics along with an unusual coupling between torque and axial deformation.

3. Multi-scale and multi-physics stochastic analysis of laminated composites and sandwich structures
This work is carried out in collaboration with University of Aberdeen, UK and Leibniz Institute for Polymer Research Dresden, Germany. The main focus is to analyze the stochastic dynamics, stability and failure of laminated composite structures based on finite element method with spatially varying randomness in the system parameters (both probabilistic and non-probabilistic approaches). The effect of various uncertain environmental effects such as temperature and moisture are analyzed. For accounting the spatially random system properties, we have proposed a generic concept of stochastic representative volume element (SRVE). We have developed a semi-analytical mechanics-based probabilistic framework to model spatially varying matrix-cracking damage in composites. The major contributions are summarized below:
- Multi-scale dynamic, stability and failure analysis of composite laminates and sandwich structures with spatially varying correlated system properties (layer-wise random variable and random field based modeling)
- Probabilistic quantification for the coupled effect of manufacturing uncertainties and service-life conditions such as progressive damage (matrix cracking and delamination), environmental and operational aspects
- Low velocity impact analysis in composite structures in the stochastic regime
- Non-probabilistic analysis (fuzzy uncertainty propagation) of composites with spatially varying micromechanical properties
- Sensitivity analysis for different micro and macro-mechanical input parameters to understand their relative influences
- Development of surrogate based finite element models for composites to achieve computational efficiency and quantification of the effect of noise in such surrogate based uncertainty propagation algorithms
4. Stochastic analysis of functionally graded materials and structures
This work is carried out in collaboration with National Institute of Technology Silchar, India and Swansea University, UK. The focus of this research project is to analyze the stochastic dynamic characteristics of functionally graded material (FGM) plates and shells under elevated temperature. Along with the graded variation of material properties across the thickness in FGM, we have introduced the aspect of spatial variability considering practically relevant statistical correlations based on Karhunen–Loève expansion. We have investigated the effect of practical design considerations such as cutouts on the stochastic dynamics, impact and stability characteristics of FGM structures.
5. Nano-mechanics of 2D materials and heterostructures
My research in nano-scale is focused on fundamental analytical development in the field of two dimensional materials and their heterostructures (nano-scale metamaterials). I have developed computationally efficient mechanics based closed-form expressions for the elastic moduli of generic hexagonal nanostructures (such as graphene, hBN and stanene) and their heterostructures. Another active field of my research is probabilistic characterization of the mechanical properties of different nano-materials based an efficient surrogate assisted Monte Carlo simulation approach. I am interested in continuum based models in nano-scale which are often validated using molecular dynamics simulations (Collaborators: Missouri University of Science and Technology, USA and Stanford University, USA).
6. Optimum design of structural and materials systems including the effect of uncertainty
I am interested in identifying the material microstructures and structural configurations (both material distribution and geometric attributes) of mechanical systems based on application-specific requirements involving multi-scale and multi-physics optimization. I have proposed an efficient high dimensional model representation based optimization algorithm for identifying the optimum structural configuration of web-core sandwich bridge decks. I have developed a non-probabilistic topology optimization approach for optimum design of composite bridges for applications in practical situations where the probabilistic descriptions of uncertain input parameters are not available. Besides that, my research in the area of optimization also involves different concepts of optimization such as reliability based optimization, robust optimization, and sensitivity based optimization in the context to structural and material systems. I have investigated various optimization algorithms along with different surrogate models to access their capability from the viewpoint of accuracy and computational efficiency.
7. Master’s thesis: Model updating and system identification
I worked in the area of vibration based structural health monitoring in my master’s thesis. I developed a computationally efficient damage identification algorithm based on surrogate assisted model updating. In this project, the capability of different response surface models in structural damage identification was assessed on the basis of accuracy and computational efficiency. I proposed an iterative multivariate adaptive regression splines (MARS) based damage identification for composite bridge decks. Performance of the surrogate based damage identification algorithms were investigated under the influence of inevitable external noise. I carried out a reliability analysis based on the accuracy of the proposed damage identification algorithm.

8. Efficient meta-model based uncertainty quantification and reliability analysis of structural systems
An active field of my research is meta-model based uncertainty quantification and reliability analysis of computationally intensive structural systems. In this approach, the expensive simulation model can be effectively replaced by an efficient mathematical/ statistical model (meta-model) resulting in a significant reduction of computational cost and time for carrying out iterative analyses such as Monte Carlo simulation. We have developed codes for various meta-modeling algorithms (such as polynomial regression, kriging, high dimensional model representation, polynomial chaos expansion, artificial neural network, moving least square, support vector regression, multivariate adaptive regression splines, radial basis function and polynomial neural network) and investigated their comparative performances in prediction from the viewpoint of accuracy and efficiency under the influence of noise.
