Post Doctoral Fellow (IISc Bangalore 2021 -2022): Development of a VAM-coupled stochastic reduced model aims to effectively determine the influence of micro structural uncertainty in heterogeneous bodies. This model enables comprehensive analysis of the effects of uncertain micro structural parameters, facilitating better understanding and predictions in such complex systems.
Institute Post Doctoral Fellow (IIT Bombay 2018 -2021):
As part of this PDF program, I had developed a computational framework of Variational Asymptotic Method (VAM) to study the influence of interface characteristics of three phase composites at micro and macroscopic scale level. The superiority of this developed homogenization model are :
Can be used more easily for any constitutive properties based modelled material micro structures.
No external loading will be required and the complete set of effective properties can be computed within one simulation.
The fluctuation function and local field can be uniquely computed.
No additional post processing computational homogenization will be required like FEA so that it will be computationally more efficient than normal FEA.
The dimensionality of the problem can be reduced by the periodicity of the material in the micro structures.
Visiting Researcher (Polish Academy of Science, Warsaw, 2016)
Institute of Fundamental Technological Polish Academy of Science, Warsaw, Poland (July 2016 - September 2016): As part of this visit, my work was to :
Reconstruct the realistic micromechanical model of metal ceramic composites from scanning electron microscope image.
Predict the realistic failure mode of composite subjected to considering imperfect interface hypothesis of discontinuity among those constituents phase boundaries.
Compute the actual interfacial properties of this composites such as cohesive strength and fracture energy based on the reverse approach.
