Amartya Bhattacharjee, Ph.D.

Senior Engineer

Dr. Amartya Bhattacharjee is a Senior Engineer at Veryst Engineering.  Dr. Bhattacharjee’s technical expertise is in the domains of solid mechanics, material modeling, fracture mechanics, structural analysis, and structural dynamics.  His research has included the fracture and fragmentation of ceramics to aid in lightweight armor material development.  He has developed analytical and numerical (MATLAB) models for crack growth, coalescence, and fragmentation under high-rate loading.  In addition, he has conducted nonlinear finite element analysis (FEA) simulations of impact experiments in Abaqus, explored the sensitivity of material model parameters on FEA simulation outputs, and performed fragment image analysis to explore the link between material microstructure and fragment morphology.  Dr. Bhattacharjee has also used boundary collocation methods and FEA simulations to study the size effect of concrete under compression.

Dr. Bhattacharjee earned an award for the best poster presentation in the Mach Conference 2019 at the Hopkins Extreme Materials Institute at Johns Hopkins University.  Two of his papers were also selected as ‘best papers’ for the Journal of the American Ceramic Society.
