Characterisation of LCF performance of X100 weld-joints: Mechanistic yield strength modelling, finite element analyses and DIC testing
(Elsevier, 2021-03-26)This paper is concerned with the effect of welding on the fatigue behaviour of X100 material for steel catenary risers. The methodology includes both modelling and experimental characterisation. The modelling combines (i) ... -
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ... -
A critical analysis of plastic flow behaviour in axisymmetric isothermal and Gleeble compression testing
(Elsevier ScienceDirect, 2010-08-16)Coupled thermo-mechanical finite element modelling of both isothermal axisymmetric compression and compression testing using the Gleeble thermo-mechanical simulator has been carried out in order to compare the levels of ... -
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 ... -
Effect of high-temperature corrosion on the service life of P91 piping in biomass co-firing
(American Society of Mechanical Engineers (ASME), 2016-02-24)Co-firing biomass with traditional fuels is becoming increasingly relevant to thermal power plant operators due to increasingly stringent regulations on greenhouse gas emissions. It has been found that when biomass is ... -
Finite element simulation and experimental validation of fretting wear
(Elsevier, 2003-10-30)A finite element-based method is presented for simulating both the fretting wear and the evolution of fretting variables with number of wear cycles in a cylinder-on-flat fretting configuration for application to aeroengine ... -
Micromechanical finite element modelling of thermo-mechanical fatigue for P91 steels,
(Elsevier, 2016-01-21)In this paper, the cyclic plasticity and fatigue crack initiation behaviour of a tempered martensitic ferritic steel under thermo-mechanical fatigue conditions is examined by means of micromechanical finite element modelling. ... -
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 ... -
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-07)Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ... -
