These microstructural changes strongly modify the mechanical properties, leading in particular to significant hardening and strain localization at the grain scale. The effects of irradiation on the mechanisms of ductile fracture - void growth and coalescence - are assessed in this study based on model experiments. Pure copper thin tensile samples have been irradiated with ions, showing a strong increase of hardness. Micron-scale holes drilled through the thickness of these samples subjecting to uniaxial loading conditions allow a detailed description of void growth and coalescence. Results are compared to those obtained on unirradiated materials, as well as to theoretical and numerical predictions. 000014179 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014179 653__ $$a 000014179 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014179 720__ $$aHure, Jeremy 000014179 8560_ $$ffischerc@itam.cas.cz 000014179 8564_ $$s64876$$uhttps://invenio.itam.cas.cz/record/14179/files/PO.SM03-1.06.208.pdf$$yOriginal version of the author's contribution as presented on CD, page 1852, code PO.SM03-1.06.208 . 000014179 962__ $$r13812 000014179 980__ $$aPAPER
