Journal ArticleDOI
Influence of a negative r ratio on the creep‐fatigue behaviour of the n18 nickel base superalloy
TL;DR: In this paper, a finite element analysis is conducted to predict the evolution of the opening stress level as a function of the stress ratio, and the influence of the constitutive equation of the material on the crack closure level is tested and the effects of kinematic hardening and viscosity are more specifically examined.
Journal ArticleDOI
Polycrystal modelling of fatigue: Pre-hardening and surface roughness effects on damage initiation for 304L stainless steel
TL;DR: In this paper, a polycrystal plasticity model, implemented in a Finite Element (FE) code, is adapted to cyclic loading, and three different fatigue criteria (Manson-Coffin, Fatemi-Socie and Dissipated Energy) have been computed.
Journal ArticleDOI
Thermo-mechanical FE model with memory effect for 304L austenitic stainless steel presenting microstructure gradient
TL;DR: In this paper, the authors investigated the surface finish effect on fatigue behavior at the inner surface of a tubular specimen submitted to thermo-mechanical fatigue by using finite element analysis (FE).
Journal ArticleDOI
Crack closure effect on crack growth rate at 650°c in double notched specimens of a nickel base superalloy
TL;DR: In this paper, the deformation mechanisms observed by TEM at the notch root are shown to be compatible with the constitutive set of equations used in the finite element analysis which is presented.
Journal ArticleDOI
Mechanical and fracture behaviour of porous materials
TL;DR: In this paper, the elastic moduli of porous materials represented as a combination of spherical, cylindrical or disk shaped holes or solid elements was calculated using a self consistent method and a yield criterion was found by stating that the elastic distortion energy evaluated with these moduli was equal to a critical value.
