Figure: A finite element simulation of mode I fracture in graphene-reinforced epoxy. Bulk finite elements are separated by cohesive elements (shown in blue in the inset) with cohesive laws computed from molecular dynamics.

Description: A variety of techniques are being used to study static and dynamic fracture mechanics from a fundamental atomistic perspective. These include full molecular dynamics, multiscale quasicontinuum, cohesive zone finite elements, and phase field. A range of problems are being studied. Examples incude:
