Molecular Dynamics-Based Cohesive Zone Model for Mg/Mg17Al12 Interface [PDF]

open access: yesMetals, 2020
The fracture of the Mg/Mg17Al12 interface was investigated by molecular dynamics simulations. The interface crack extends in a brittle manner without noticeable plasticity.

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

open access: yesScientific 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 ...

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

open access: yesZhongguo 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

open access: yesLubricants, 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

open access: yesApplied 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

open access: yesMetals, 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

open access: yesNihon 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

open access: yesYantu 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 ...

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.
