Numerical simulation of fatigue crack growth rate and crack retardation due to an overload using a cohesive zone model [PDF]

, 2014
In this work, a numerical method is pursued based on a cohesive zone model (CZM). The method is aimed at simulating fatigue crack growth as well as crack growth retardation due to an overload.

Cohesive zone model for ductile fracture

, 1994
A cohesive zone model (CZM) is used for simulating ductile crack growth. Some new aspects and assumptions are introduced in the CZM and applied in conjunction with the finite element method (FEM).

Cohesive zone modeling of mode I fracture in adhesive bonded joints

, 2007
This paper deals with the application of Cohesive Zone Model (CZM) concepts to study mode I fracture in adhesive bonded joints. In particular, an intrinsic piece-wise linear cohesive surface relation is used in order to model fracture in a pre-cracked ...

Study of temperature-dependent interface with viscoelastic behavior through shear testing and modeling

Polymer Testing
In this work, the effect of temperature on interfaces with viscoelastic behavior was investigated using experimental and theoretical means. In particular, rubber/woven fabrics with thickness of 0.5 mm were subjected to self-designed shear tests at ...

A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging

, 2017
A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever ...

A simple method to model crack propagation in concrete [PDF]

Constructii: Journal of Civil Engineering Research, 2012
Crack analysis is vital to explain behavior of concrete structures. In the present study, an interface element with softening spring is used to simulate cohesive zone model (CZM) in beam to accurately explain the propagation for mixed-mode crack ...
