Multiscale analysis of the effect of debris on fretting wear process using a semi-concurrent method [PDF]
, 2020 Fretting wear is a phenomenon, in which wear happens between two oscillatory moving contact surfaces in microscale amplitude. In this paper, the effect of debris between pad and specimen is analyzed by using a semi-concurrent multiscale method.

Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation [PDF]
Инженерно-строительный журнал, 2011 Fatigue strength evaluation of non-continuous incomplete penetration fillet-welded joints transferring stress flow by the S-N criteria incorporating the «Hot-spot stress» or «Notch-stress» approaches is dubious since the characteristic stress at the ...

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 ...
