An experimental methodology is developed to evaluate size effects in nanovoids deformation under macroscopic uniaxial stress loading conditions. Quantitative evaluation of voids deformation as a function of voids size shows both a crystallographic ef

Theoretical estimates for flat voids coalescence by internal necking

Autor: Hure, J., Barrioz, P. O.

Coalescence of voids by internal necking is in most cases the last microscopic event related to ductile fracture and corresponds to a localized plastic flow between adjacent voids. Macroscopic load associated to the onset of coalescence is classicall

International audience; The growth of nanovoids in crystalline metallic material is assessed experimentally as a function of the applied macroscopic plastic strain, stress triaxiality and crystal orientation. Nanovoids - of diameter ranging from 20 t
