The Cohesive Zone Model for Fatigue Crack Growth
Advances in Mechanical Engineering, 2013 In the past decade, the cohesive zone model has been receiving increasing attention as a powerful tool for the simulation of fatigue crack growth. When applying cohesive zone model to fatigue fracture problem, three aspects should generally be taken into

Frequency-Dependent Cohesive Zone Models for Fatigue [PDF]
Journal of Physics: Conference Series, 2017 This paper is concerned with a new cohesive zone model (CZM) to better describe the effects of rate and cyclic loading. Rate is known to affect the manner in which cracks propagate in materials, yet there presently exists no rate-dependent cohesive model for fatigue simulation.

THE EFFECT OF CRITICAL TRACTION IN COHESIVE ZONE MODEL FOR FATIGUE CRACK GROWTH RETARDATIO [PDF]
Media Mesin, 2016 A cohesive zone model for simulation of fatigue crack growth is presented. The cohesive zone model is one of many alternative approaches used to simulate fatigue crack growth. The model incorporates a relationship between cohesive traction and separation

Finite element simulation of delamination growth in composite materials using LS-DYNA [PDF]
, 2009 In this paper, a modified adaptive cohesive element is presented. The new elements are developed and implemented in LS-DYNA, as a user defined material subroutine (UMAT), to stabilize the finite element simulations of delamination propagation in ...

A discontinuous Galerkin method for cohesive zone modelling [PDF]
Finite Elements in Analysis and Design, 2015 We propose a discontinuous finite element method for small strain elasticity allowing for cohesive zone modeling. The method yields a seamless transition between the discontinuous Galerkin method and classical cohesive zone modeling. Some relevant numerical examples are presented.

A fractional rate‐dependent cohesive‐zone model [PDF]
International Journal for Numerical Methods in Engineering, 2015 SummaryThis paper presents a novel formulation of a hereditary cohesive zone model able to effectively capture rate‐dependent crack propagation along a defined interface, over a wide range of applied loading rates and with a single set of seven input parameters only, as testified by the remarkable agreement with experimental results in the case of a ...

Cohesive zone models in history dependent materials [PDF]
, 2013 Copyright @ 2013 ACMECohesive zone model is a well known concept in nonlinear fracture mechanics of elasto-plastic materials. In contrast to that, we discuss a development of the cohesive zone model to linear, but time and history dependent, materials ...

Cohesive zone failure modeling of polymeric adhesives used in ceramic/metal armor [PDF]
, 2022 In this paper, a trilinear cohesive zone modeling approach available in the explicit nonlinear finite element software LS-DYNA is used to model the dynamic impact failure of an adhesive layer.

Multi-timescale analysis of fatigue crack growth on interfaces via cohesive-zone models [PDF]
, 2014 The paper describes a new non-linear finite-element formulation to analyse fatigue debonding or delamination, along predefined interfaces, which is multi-scale in time. At the small timescale level, cyclic loading and the related oscillating response are

Testing some implementations of a cohesive-zone model at finite strain [PDF]
, 2015 This study shows how the results given by a cohesive-zone model at finite strain may depend strongly on its numerical implementation. A two-dimensional four-node cohesive element is considered, which includes several variants depending on a part of the ...
