TL;DR: In this article, an extension of the celebrated Paris law for crack propagation is given to take into account some of the deviations from the power-law regime in a simple manner using the Wohler SN curve of the material, suggesting a more general ''unified law''.

TL;DR: In this paper, the authors introduce a new failure criterion in the framework of finite fracture mechanics, which relies on the assumption that the finite distance is not a material constant but a structural parameter.

TL;DR: In this article, a modification to the traditional Griffith energy balance as used in linear elastic fracture mechanics (LEFM) is described, which involves using a finite amount of crack extension instead of an infinitesimal extension (da) when calculating the energy release rate.

TL;DR: In this paper, the authors used a recently introduced finite fracture mechanics (FFM) criterion, i.e., a fracture criterion assuming that crack grows by finite steps, and the length of this finite extension is determined by a condition of consistency of both energy and stress requirements; as consequence, the crack advancement is not a material constant but a structural parameter.

TL;DR: In this article, the authors use the local fractional calculus operators introduced by K.M. Kolwankar to obtain the static and kinematic equations that model the uniaxial tensile behavior of heterogeneous materials.
