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 ...

The Cohesive Zone Model Applied to Blunt Cracks [PDF]

, 2014
Many practical situations involve blunt cracks, which have a finite tip radius and no stress singularity due to the presence of a notch or self-blunting behavior. In these cases, linear elastic fracture mechanics does not apply.

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 ...

Fatigue crack growth prediction in polymer composites using XFEM cohesive segments

Academia Materials Science
Introduction: Fatigue damage remains a major challenge in the design of composite structures, as cracks may initiate under low stress levels and evolve through multiple interacting failure mechanisms.

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 (CZM) in prediction of delamination failure in laminated composite structures [PDF]

, 2011
The ply delamination which is known as a principle mode of failure of layered composites due to separation along the interfaces of the layers is one of the main concerns in designing of composite material structures.

Failure Analysis of Brazed Joints Using the CZM Approach [PDF]

, 2011
Brazing, as a type of joining process, is widely used in manufacturing industries to join individual components of a structure. Structural reliability of a brazed assembly is strongly dependent on the joint mechanical properties.
