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 ...

Predicting mode II delamination suppression in z-pinned laminates [PDF]
, 2012 A finite element model for predicting delamination resistance of z-pin reinforced laminates under the mode-II load condition is presented. End notched flexure specimen is simulated using a cohesive zone model.

Some features of the PPR cohesive-zone model combined with a linear unloading/reloading relationship [PDF]
, 2017 A loading/unloading/reloading process is applied to a cohesive zone where the model proposed by Park, Paulino and Roesler in 2009 is combined with a linear unloading/reloading relationship.

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.

Effect of H2 on Blast Furnace Ironmaking: A Review
Metals, 2022 Under the background of “carbon peaking” and “carbon neutralization”, the green transformation of iron and steel enterprises is imminent. The hydrogen-rich smelting technology of blast furnaces is very important for reducing energy consumption and CO2 ...

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

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 new cohesive model for simulating delamination propagation in composite laminates under transverse loads [PDF]
, 2008 In this paper, we propose a new cohesive model to stably and accurately simulate the\ud delamination propagations in composite laminates under quasi-static and low-velocity\ud impact transverse loads using comparatively coarse meshes.
