Non-smooth contact dynamics approach of cohesive materials

open access: yes, 2001
International audienceThe main features of the non-smooth contact dynamics (NSCD) method—the dynamical equation, the Signorini relation as a non-smooth modelling of unilateral contact, and the frictional Coulomb's law, treated with fully implicit ...

Monitoring power-law creep using the failure forecast method

open access: yes, 2018
Creep is considered to be the life limiting damage mechanism in many load bearing high temperature components. A range of different parameters determine the creep life of a component, many of which are unlikely to be known to sufficient accuracy to ...

Modeling the mechanics of amorphous solids at different length and time scales

open access: yes, 2011
We review the recent literature on the simulation of the structure and deformation of amorphous glasses, including oxide and metallic glasses. We consider simulations at different length and time scales. At the nanometer scale, we review studies based on

Gradient damage models and their use in brittle fracture [PDF]

open access: yes, 2016
The paper is devoted to gradient damage models which allow us to describe all the process of degradation of a body including the nucleation of cracks and their propagation.

Transfer function concept for ultrasonic characterization of material microstructures [PDF]

open access: yes
The approach given depends on treating material microstructures as elastomechanical filters that have analytically definable transfer functions. These transfer functions can be defined in terms of the frequency dependence of the ultrasonic attenuation ...
