Simulation of delamination in composites under high-cycle fatigue (2007, background): “Cohesive finite elements have been developed to capture the initiation and propagation of delamination cracks [8,13,14,19–28].”
A fatigue degradation law for cohesive interface elements – Development and application to composite materials (2010, background): “As well as providing potential to simulate impact damage and subsequent fatigue crack propagation within a single coherent simulation, use of an explicit solver can also avoid convergence problems, often encountered in implicit analyses when modelling strongly non-linear events [4].”
A stable mesh-independent approach for numerical modelling of structured soils at large strains (2019, methodology): “ness matrix of the Newton-Raphson method may become so illconditioned that no convergence might be achieved even if using very small time-steps (Alfano and Crisfield, 2001; Lorentz and Badel, 2004; Oliver et al., 2008; Lu et al., 2009).”
Modelling adhesive joints with cohesive zone models: effect of the cohesive law shape of the adhesive layer (2013, neutral): “Developed CZM include triangular [17], linear-parabolic [18], polynomial [19], exponential [20] and trapezoidal laws [21].”
Methods for the prediction of fatigue delamination growth in composites and adhesive bonds: A critical review (2013, methodology): “The evolution of this damage parameter followed the relation proposed by Peerlings et al.

Accurate simulation of delamination growth under mixed-mode loading using cohesive elements: Definition of interlaminar strengths and elastic stiffness (2010, methodology): “The most common approaches that have been proposed to simulate delamination are the Virtual Crack-Closure Technique (VCCT), either by post-processing finite element results [3] or by using special-purpose VCCT elements [4], and cohesive finite elements [5–11].”
A concise interface constitutive law for analysis of delamination and splitting in composite materials and its application to scaled notched tensile specimens (2007, background): “Since composite delamination processes often involve strong non-linear events such as snap-back and snap-through, convergence is usually very difficult to achieve if the simulations are performed using an implicit code without complex path following algorithms [9].”
