The influence of void morphology and loading conditions on deformation and failure of porous polymers: A combined finite-element and analysis of variance study
Andrea Spaggiari,Noel P. O’Dowd +1 more
TL;DR: In this article, a combined finite element and analysis of variance study of polymeric materials containing spherical and ellipsoidal voids is presented, which simulates an infinite medium of the material containing an array of voids, using three dimensional finite element analysis.
Interfacial fracture toughness of alumina/niobium systems
TL;DR: In this paper, the interfacial fracture toughness of an alumina/niobium composite has been measured as a function of phase angle, and it was found that the toughness increased with loading phase angle to a value of K{sub c} {approx} 9 MPa{radical}m at a phase between 25 and 40 degrees.
Journal ArticleDOI
Combined finite element and phase field method for simulation of austenite grain growth in the heat-affected zone of a martensitic steel weld:
TL;DR: In this paper, the effects of microstructural cracks in the heat-affected zone adjacent to a weld are investigated. And the authors propose a method to detect and prevent the initiation and growth of cracks in this zone.
Journal ArticleDOI
Computational modelling of crack initiation in a single crystal superalloy under fatigue-oxidation conditions
TL;DR: In this paper, a single crystal nickel base superalloy was studied under fatigue-oxidation conditions, using a crystallographic constitutive theory in conjunction with a mass diffusion model, and the number of cycles to crack initiation was predicted using a strain ratchetting based failure criterion.
Journal ArticleDOI
Review of a procedure for performing constraint and attenuation-corrected fracture mechanics safety case calculations for Magnox reactor steel pressure vessels
R.E. Dolby,C.S. Wiesner,Robert A. Ainsworth,F.M. Burdekin,J. W. Hancock,I. Milne,Noel P. O’Dowd +6 more
TL;DR: In this paper, an assessment methodology put forward by BNFL Magnox Generation to take account of effects of constraint and dose attenuation in determining the margin between onset of upper shelf temperature (OUST) and normal steady state service temperature has been examined in detail by the UK Technical Advisory Group on Structural Integrity of Nuclear Plant (TAGSI).
