Computational study on the effect of contact geometry on fretting behaviour
(Elsevier ScienceDirect, 2011-07-23)A key challenge in the design of engineering couplings and contacting components relates to the development of an understanding of the comparative performance of contrasting contact geometries for a given application, ... -
Experimental characterisation, computational modelling and design tool development for fretting fatigue and wear in flexible marine risers
(2017-09-25)Fretting is a key concern in the fatigue design of the pressure armour layer of flexible marine risers, due to the combination of extreme global dynamic loading conditions and the local geometrical-tribological conditions ... -
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) ... -
Micromechanical modelling of size effects in crack initiation with application to fretting fatigue and cold dwell fatigue
(NUI Galway, 2018-12-19)This thesis presents the development of a micromechanical computational framework for microstructure sensitivity of crack initiation in metals, with application to fretting fatigue and cold-dwell facet fatigue. It is ... -
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ... -
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ... -
A Study of Microstructure-Sensitive Crack Nucleation and Wear in Fretting
(2013-07-08)This thesis presents the development of a computational and experimental methodology for predicting crack initiation and wear in fretting of engineering materials. A bridge-type fretting fatigue test rig is designed and ...
