A comparison of finite element and atomistic modelling of fracture
Valerie R Coffman, James P. Sethna, Gerd Heber +4
Are the cohesive laws of interfaces sufficient for modelling fracture in polycrystals using the cohesive zone model? We examine this question by comparing a fully atomistic simulat…

Grain boundary energies and cohesive strength as a function of geometry
Valerie R. Coffman, James P. Sethna
Cohesive laws are stress-strain curves used in finite element calculations to describe the debonding of interfaces such as grain boundaries. It would be convenient to describe grai…
