Enhanced cohesive zone model to predict delamination behavior of carbon/epoxy laminated curved beams [PDF]
, 2022 This paper proposes an enhanced Cohesive Zone Model (CZM) for the prediction of delamination in curved beams of epoxy carbon laminates. This model improves the conventional CZM, taking into account the fiber-bridging phenomenon and the variation of the ...

Finite element modelling of mode I delamination specimens by means of implicit and explicit solvers [PDF]
, 2012 The simulation of delamination using the Finite Element Method (FEM) is a useful tool to analyse fracture mechanics. In this paper, simulations are performed by means of two different fracture mechanics models: Two Step Extension (TSEM) and Cohesive Zone

A Cohesive Zone Model for Three-dimensional Fatigue Debonding/Delamination [PDF]
, 2014 The cohesive zone model (CZM) has found a wide acceptance as a tool for the simulation of delamination in composites and debonding in bonded joints. Recently, fatigue-devoted implementations of CZM have been proposed.

Numerical aspects of phase field models for low-temperature fracture in asphalt mixtures
Case Studies in Construction Materials, 2023 Unlike the cohesive interface element model, the phase field model (PFM) is a newly developed computational model which provides a unified approach to predicting crack nucleation, propagation, coalescence and branching without any ad-hoc criterion.
