Abstract

An interface energy term is presented that allows for internal surfaces, such as grain boundaries to follow their own yield behavior upon the application of external loads. Interface yielding can be defined as the onset of interaction between the grain boundary and dislocations from the adjoining grains, it can therefore account for intergranular fracture. Atomistic, density dislocation function dynamics simulations and nanoindentation experiments are presented herein to define and calculate such interface energy terms for aluminum and Fe-Si.
