Numerical simulation of fatigue crack propagation in heterogeneous geomaterials under varied loads using displacement discontinuity method

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Heterogeneous brittle geomaterials are highly susceptible to cyclic loads. They contain inherent flaws and cracks that grow under fatigue loads and lead to failure.

Dislocation Modelling of Fatigue Cracks: An Overview

MATERIALS TRANSACTIONS, 2001
The intrinsic threshold behavior of fatigue cracks and the disappearance of any cyclic plastic deformation below a threshold value can be understood by taking into account the discreteness of plasticity with recourse to discrete dislocation models. The aim of this paper is to document the progress in the discrete dislocation modelling within the past ...
