Homogenization and Path Independence of the J-Integral in Heterogeneous Materials [PDF]
, 2016 The J-integral that determines the driving force on a crack tip is a central concept of fracture mechanics. It is particularly useful since it is path independent in homogeneous materials. However, most materials are heterogeneous at a microscopic scale,
