Fatigue crack shielding in plain bearings under large scale yielding

open access: yes, 2010
Multi-layered bearing systems used in the automotive industry show shielding and antishielding effects that reduce or amplify the crack driving force under large-scale yielding conditions. Using finite element analysis, it is shown that shielding in such

Numerical modelling of three-dimensional fatigue crack closure: mesh refinement. [PDF]

open access: yes, 2018
Accepted ManuscriptFatigue crack closure has been studied by means of the finite element method for a long time. Most work has been performed considering bi-dimensional models where the numerical methodology has been developed.

Crack coalescence and brittle failure characteristics of open rock bridges

open access: yesYantu gongcheng xuebao, 2020
The coalescence of rock bridge of fractured rock mass with end cracking is the main cause of the sudden damage of the rock mass, and the brittle failure is obvious.

Three-Dimensional Elastic-Plastic Finite Element Analysis of Fatique Crack Growth and Closure [PDF]

open access: yes, 1986
The purpose of this study was to develop a three-dimensional, elastic-plastic, finite element analysis to investigate crack extension and closure under cyclic loading. The initial study concentrated on the behavior of a straight through crack in a finite-

Implementation of a Plastically Dissipated Energy Criterion for Three Dimensional Modeling of Fatigue Crack Growth [PDF]

open access: yes, 2013
Fatigue crack growth is simulated using three dimensional elastic-plastic finite element analysis. The crack extension per load cycle, da/dN, as well as crack front profile changes (crack tunneling) under cyclic loading is not specified as an input but ...
