A multi-scale crystal plasticity model for cyclic plasticity and low-cycle fatigue in a precipitate-strengthened steel at elevated temperature
(Elsevier, 2016-12-24)
In this paper, a multi-scale crystal plasticity model is presented for cyclic plasticity and low-cycle fatigue in a tempered martensite ferritic steel at elevated temperature. The model explicitly represents the geometry ...
Strain-gradient modelling of grain size effects on fatigue of CoCr alloy
(Elsevier, 2014-07-30)
A strain-gradient crystal plasticity framework based on physical dislocation mechanisms is developed for simulation of the experimentally observed grain size effect on the low cycle fatigue of a CoCr alloy. Finite-element ...
Development of life assessment procedures for power plant headers operated under flexible loading scenarios
(Elsevier ScienceDirect, 2013-12-22)
A finite element methodology for thermo-mechanical fatigue analysis of a subcritical power plant outlet header under realistic loading conditions is presented. The methodology consists of (i) a transient heat transfer ...
Micro-scale testing and micromechanical modelling for high cycle fatigue for CoCr stent material
(Elsevier ScienceDirect, 2015-02-20)
This paper presents a framework of experimental testing and crystal plasticity micromechanics for high cycle fatigue (HCF) of micro-scale L605 CoCr stent material. Micro-scale specimens, representative of stent struts, are ...
