The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

The Variational Approach to Fracture (2008, background): “This apparently innocuous observation delivers, in our opinion, a devastating blow to a whole slew of models – especially popular among numerical mechanicians – that propose to tackle fracture through the introduction of surface energies with 0-slopes; see [27, 94].”
An open-source Abaqus implementation of the phase-field method to study the effect of plasticity on the instantaneous fracture toughness in dynamic crack propagation (2020, methodology): “Various modifications [34,40,41] were proposed to circumvent these issues.”
A non‐linear interface element for 3D mesoscale analysis of brick‐masonry structures (2011, background): “When cracks develop and spread along the structure, the elastic energy stored in the bulk material connected to a damaged interface has to be redistributed into other elements, leading in certain cases to very sharp snap-backs and solution jumps in the static global response [15].”
The Mori–Tanaka method for composite materials with nonlinear interface debonding (2005, background): “Such a phenomenon has also been observed in other cohesive finite element simulations (Walter et al., 1997; Zhong and Knauss, 1997; Chaboche et al., 2001).”
