Summary of Activities/Interests

Professor Khandelwal is interested in how infrastructural systems (e.g., buildings, bridges) behave under extreme loading conditions. These conditions may be man-made or generated by natural hazards, such as seismic excitation, impact and blast. He is currently investigating how to utilize new materials and technologies together with multi-scale structural optimization methods to create innovative structural systems that mitigate effects of extreme loading. Much of his research is focused on the computational and theoretical aspects of structural engineering, with particular emphasis on multiscale computational simulations including finite element methods, structural optimization, constitutive modeling, damage-plasticity formulations, nonlinear solution strategies and advanced visualization techniques.
