In this work, an experimental measurement, contour method, is implemented for an after quenching IN718 forging specimen to obtain the distribution of residual stress field. A sequentially coupled thermal mechanical finite element model is developed w

Purpose The purpose of this paper is to systematically investigate the dynamic strain aging (DSA) effect in solid solution treated IN718 at different temperatures through experiments and simulations to gain an understanding of the inelastic deformati

The effects of dynamic strain aging (DSA) on residual stresses generated in Ni-base superalloys during heat treatments are not well understood. In this study, the residual stress field induced by water quenching an IN718 disc while undergoing DSA is

International audience; Mindlin's second strain gradient continuum theory for isotropic linear elastic materials is used to model two different kinds of size-dependent surface effects observed in the mechanical behaviour of nano-objects. First, the e

This work presents a new formalism for a time-dependent (or incremental) fatigue damage model developed for single-crystal nickel-based superalloys. The proposed coupled damage viscoplastic formulation accounts for the damage associated with microcra

International audience; This work concerns a study of the mechanisms responsible for intergranular cracking during high temperature stress relaxation in AISI 316L-type austenitic stainless steels. This phenomenon, also known as reheat cracking, is ty

In this paper, a novel micromechanics-based constitutive model is proposed for linear viscoelastic particle-reinforced composites based on a homogenization approach in the time domain. After decomposing the deformation into its volumetric and deviato
