Computational Simulation of 3D Fatigue Crack Growth under Mixed-Mode Loading [PDF]
Applied Sciences, 2021 The purpose of this research was to present a simulation modelling of a crack propagation trajectory in linear elastic material subjected to mixed-mode loadings and investigate the effects of the existence of a hole and geometrical thickness on fatigue ...

Fatigue crack growth under large scale yielding condition: a tool based on explicit crack growth [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2023 Fatigue crack growth under large-scale yielding condition is studied for high-temperature loading. The applied strains are so important that diffuse damage phenomena are visible as a network of micro-cracks in front of the major crack.

Influence of forging conditions on the fatigue mechanisms of low alloy steels: a 3D study [PDF]
Fracture and Structural Integrity, 2017 The influence of forging conditions on the propagation of physically small fatigue cracks has been studied for two high strength steels. Two surface conditions were produced after the forging process.

An X-FEM based framework for 3D fatigue crack growth using a B-spline crack geometry description
Engineering Fracture Mechanics, 2022 This paper presents an X-FEM based iterative framework for numerical simulation of threedimensional fatigue crack propagation. To accurately describe the crack geometry, B-spline curves and surfaces are used for the crack front and faces respectively.

International Journal of Fracture, 2023 AbstractMany structural components and devices in combustion and automotive engineering undergo highly intensive cyclic thermal and mechanical loading during their operation, which leads to low cycle (LCF) or thermomechanical (TMF) fatigue crack growth. This behavior is often characterized by large scale plastic deformations and creep around the crack,

Finite Elements in Analysis and Design, 2022 The present work proposes a novel efficient numerical approach for the simulation of three-dimensional propagation of non-planar frictional crack under Rolling Contact Fatigue (RCF). The developed model relies on a global–local strategy involving the Semi-Analytical Method (SAM), dedicated to the resolution of 3D contact problems, and the eXtended ...

3D thickness effects around notch and crack tip stress/strain fields [PDF]
Fracture and Structural Integrity, 2015 Notches and cracks are usually approximately modeled as two-dimensional problems using solutions from plane elasticity to quantify localized stress/strain concentration effects around their tips. However, they may be associated with high gradients that
