Finite element simulation of fretting wear and fatigue in thin steel wires
(Elsevier ScienceDirect, 2013-05-09)This paper studies the effect of fretting on fatigue life reduction of thin steel wires, using the frictionally-induced multiaxial contact stresses obtained from a finite element wear model, validated in previous work. The ... -
A finite element study of microstructure-sensitive plasticity and crack nucleation in fretting
(Elsevier ScienceDirect, 2011)This paper is concerned with finite element modelling of microstructure-sensitive plasticity and crack initiation in fretting. The approach adopted is based on an existing method for microstructure-sensitive (uniaxial) ... -
Micro-mechanical modelling of fretting fatigue crack initiation and wear in Ti-6Al-4V
(Elsevier ScienceDirect, 2013-05-02)A micro-mechanical modelling methodology is presented for predicting fretting fatigue crack nucleation in Ti–6Al–4V. The methodology is based on a combination of (i) a unit cell crystal plasticity model of Ti–6Al–4V, (ii) ... -
Micromechanical modelling of fatigue crack nucleation in stents
(Bioengineering In Ireland Conference 2012, 2012)A finite element based micro-mechanical methodology for cyclic plasticity and fatigue crack initiation in cardiovascular stents is presented. The methodology is based on the combined use of a (global) three-dimensional ...
