Evaluation of the intrinsic crack growth rates of weld joints [PDF]
, 2011 A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

Particle Equilibrium Method for Crack Propagation Simulation
Mathematical Problems in Engineering, 2018 Crack propagation simulation is constantly of great significance. This study presents the particle equilibrium method (PEM) to achieve this goal. PEM is based on the idealization of the problem domain as an assemblage of distinct particles, which release interaction forces to their surrounding particles.

Numerical investigation on the prefabricated crack propagation of FV520B stainless steel
Results in Physics, 2017 FV520B is a common stainless steel for manufacturing centrifugal compressor impeller and shaft. The internal metal flaw destroys the continuity of the material matrix, resulting in the crack propagation fracture of the component, which seriously reduces ...

A computer simulation of the crack propagation process
Materials Science and Engineering, 1986 Abstract A molecular dynamics technique based on a pair interaction model was employed to simulate the propagation of a surface crack in two-dimensional prestrained systems. Investigations include an atomistic level analysis of the crack growth process as well as the distributions of the high stress regions in the system and their associations with ...

A discrete dislocation dynamics study aiming at understanding fatigue crack initiation [PDF]
, 2003 We use discrete dislocation dynamics to build a model for fatigue crack initiation in a surface grain. Dislocations are modeled as line singularities in an elastic medium where they can be generated from pre-existing sources, glide or annihilate.
