An extended J-integral for evaluating fluid-driven cracks in hydraulic fracturing
Journal of Rock Mechanics and Geotechnical Engineering, 2018 J-integral has served as a powerful tool in characterizing crack tip status. The main feature, i.e. path-independence, makes it one of the foremost fracture parameters.

An enhanced J‐integral for hydraulic fracture mechanics
International journal for numerical and analytical methods in geomechanics (Print), 2022 This article revisits the formulation of the J‐integral in the context of hydraulic fracture mechanics. We demonstrate that the use of the classical J‐integral in finite element models overestimates the length of hydraulic fractures in the viscosity ...

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,
