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 ...

A fractional rate‐dependent cohesive‐zone model [PDF]
International Journal for Numerical Methods in Engineering, 2015 SummaryThis paper presents a novel formulation of a hereditary cohesive zone model able to effectively capture rate‐dependent crack propagation along a defined interface, over a wide range of applied loading rates and with a single set of seven input parameters only, as testified by the remarkable agreement with experimental results in the case of a ...

The Cohesive Zone Model for Fatigue Crack Growth
Advances 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

Frequency-Dependent Cohesive Zone Models for Fatigue
Journal of Physics: Conference Series, 2017 This paper is concerned with a new cohesive zone model (CZM) to better describe the effects of rate and cyclic loading. Rate is known to affect the manner in which cracks propagate in materials, yet there presently exists no rate-dependent cohesive model for fatigue simulation.

A CORRECTED COHESIVE ZONE MODEL IN THE INTERLAMINAR FRACTURE OF COMPOSITE
Jixie qiangdu, 2021 In order to consider both material damage of the crack tip and the initial fracture toughness,a corrected cohesive zone model（ CZM） that considers the influence of material damage of the initial crack propagation has been proposed. The corrected cohesive

Cohesive zone modeling of creep–fatigue crack propagation with dwell time
Advances in Mechanical Engineering, 2017 In engineering application, a quantitative description of both fatigue and creep damage mechanisms is demanded for high-temperature alloy. This work employs the cohesive zone model to numerically simulate the crack propagation in a nickel-based super ...
