The Cohesive Zone Model for Fatigue Crack Growth

open access: yesAdvances 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

A discontinuous Galerkin method for cohesive zone modelling [PDF]

open access: yesFinite 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.

Overcoming the cohesive zone limit in the modelling of composites delamination with TUBA cohesive elements [PDF]

open access: yesComposites Part A: Applied Science and Manufacturing
The wide adoption of composite structures in the aerospace industry requires reliable numerical methods to account for the effects of various damage mechanisms, including delamination. Cohesive elements are a versatile and physically representative way of modelling delamination.

Cohesive zone models in history dependent materials [PDF]

open access: yes, 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 ...

Finite element simulation of delamination growth in composite materials using LS-DYNA [PDF]

open access: yes, 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 ...

Cohesive zone failure modeling of polymeric adhesives used in ceramic/metal armor [PDF]

open access: yes, 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]

open access: yes, 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]

open access: yes, 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 ...

Finite Element Simulation of HELICOIL® Inserts

open access: yesApplied Sciences, 2022
This paper details the possibility of simulating HELICOIL® inserts using Finite Element Analysis and contact technology. The main procedure is based on the use of contact elements in the Glue–Cohesive setting, which is usually considered for the ...
