Enabled an integrative environment for the modeling of Fiber Reinforced Plastics (FRPs) employing Moldflow and in-house software, reducing dependency on commercial Finite Element (FE) software. Developed an in-house Finite Element (FE) package based on C++ and Deal.ii capable of simulating shrinkage and warpage of injection-molded Fiber Reinforced Plastics (FRPs). Study the effect of varying fiber volume fractions and fiber geometry on the material behavior of FRPs. Validated with commercial FE softwares.

Worked on multiscale simulation of polymers through the coupling of Continuum Mechanics and Particle-based Modelling. Worked on transforming a specific section of existing implementation in MATLAB to C++. Coupling of Continuum Mechanics and Molecular dynamics is achieved through the Capriccio Method - "Coupled Arlequin-based Particle-Continuum Computation".

Performed Finite Element Analysis using Abaqus/COMSOL to characterize the material behavior of polycrystalline materials. Developed a MATLAB based code to model polycrystalline material structure in 2D/3D and to simulate acoustic wave propagation employing Finite Element Analysis (FEA). Improved capacity to model microstructure - from 3,000 grains in commercial FE tools to 100,000 grains in the developed in-house tool. Performed experimental studies on Time of Flight Diffraction (TOFD).
