The primary interest of this group is to investigate behavior of different materials at different scales ranging from atomistic to continuum. The type of materials investigated involves metals, ceramics, polymers, minerals, composites and even fluids. Even though our primary interest lies in mechanical, thermal and optical characteristics of the material subjected to extreme loading conditions such as that of shock wave interaction and/or projectile impact; however, we do study behavior of materials under different types of loading conditions including quasistatic situations.
