Semi-analytical solution of cohesive zone model for cement-based materials [PDF]

Scientific Reports
The low tensile strength characteristics of cement-based materials are the biggest defect restricting their use. Understanding the mechanisms behind tensile cracking shows great significance in guiding the design of cement-based materials and their ...

Improvement of a Cohesive Zone Model for Fatigue Delamination Rate Simulation. [PDF]

Materials (Basel), 2019
The cohesive zone model (CZM) has found wide acceptance as a tool for the simulation of delamination in composites and debonding in bonded joints and various implementations of the cohesive zone model dedicated to fatigue problems have been proposed in the past decade.

Application of improved cohesive zone length formula in ice mode I crack propagation

Zhongguo Jianchuan Yanjiu, 2022
ObjectivesThe cohesive zone length is the sum of the cohesive element length at the failure edge and the lengths of the other cohesive elements connected to it. The cohesive zone length determines the maximum size of the mesh.

Modeling Adhesive Hysteresis

Lubricants, 2021
When an elastomer approaches or retracts from an adhesive indenter, the elastomer’s surface can suddenly become unstable and reshape itself quasi-discontinuously, e.g., when small-scale asperities jump into or snap out of contact. Such dynamics lead to a

A Numerical Investigation of Delamination Response of CNT/Epoxy Film Interleaved Composite

Applied Sciences, 2022
In this study, numerical modeling through the cohesive zone theory was performed to simulate the end notch flexure (ENF) test with same conditions of the experimental results of previous study that investigated the effect of a carbon nanotube (CNT)/epoxy

Applying Membrane Mode Enhanced Cohesive Zone Elements on Tailored Forming Components

Metals, 2020
Forming of hybrid bulk metal components might include severe membrane mode deformation of the joining zone. This effect is not reflected by common Traction Separation Laws used within Cohesive Zone Elements that are usually applied for the simulation of ...

Estimating the critical stress intensity factor for an interfacial corner equivalent to an interfacial crack using the molecular statics and cohesive zone model

Nihon Kikai Gakkai ronbunshu, 2021
The stress intensity factors (SIFs) for an interfacial corner, which are compatible with that for a crack, can describe the singular stress field around the corner.

Simulation for interaction between geogrids and soil by cohesive zone model

Yantu gongcheng xuebao, 2020
The cohesive zone model is widely used in the fracture numerical simulation of bonded metal members. In order to deeply analyze the interaction between geogrids and soil, the cohesive zone model is adopted at the transverse ribs of geogrids and penalty ...
