We carry out analyses of ductile crack growth with voids nucleating from discretely modeled particles so as to introduce a characteristic length. Crack growth resistance curves and fracture surface roughness measures are computed for various distributions. The results indicate that by suitably designing the particle distribution, a material’s ductile crack growth resistance can be significantly increased. 000015185 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000015185 653__ $$a 000015185 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000015185 720__ $$aSrivastava, Ankit 000015185 8560_ $$ffischerc@itam.cas.cz 000015185 8564_ $$s108369$$uhttps://invenio.itam.cas.cz/record/15185/files/TS.SM05-10.02.pdf$$yOriginal version of the author's contribution as presented on CD, page 2021, code TS.SM05-10.02 . 000015185 962__ $$r13812 000015185 980__ $$aPAPER
