The Kamrin group is headed by Prof. Ken Kamrin in the Department of Mechanical Engineering at MIT.  Our research focuses broadly on continuum mechanics, with an emphasis on highly-deforming bulk materials such as granular materials, compliant elastic solids, and viscous or viscoplastic media.  Continuum modeling, when applicable, can offer predictive power in a fraction of the time needed for full micro-level discrete simulation.  We aim to improve capabilities in the continuum by developing novel computational methods and constitutive relations. 

A significant motivational theme is to understand problems that combine fluid- and solid-like behaviors, either geometrically (as in fluid/structure interaction), or constitutively (as in elasto-viscoplastic material flow).  Some broad areas of ongoing research include:  Constitutive modeling, simulation, and homogenization of amorphous materials;  Eulerian and meshless simulation methods for finite-deformation solid laws;  reduced-dimensional models for fluid or solid behaviors; mobility theory of flows over textured surfaces. See the tabs to the right for more details about our group.
