Results suggest that the media has a much lower resistance to rupture under in-plane than under out-of-plane shear loading, while the tensile strength is lowest in the radial direction. A phase-field approach was used to computationally capture the obtained data, whereby an energy-based anisotropic failure criterion was developed to drive the crack phase-field. Finite element results of a simple shear test are shown and in favorable agreement with experimental data. 000015085 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000015085 653__ $$a 000015085 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000015085 720__ $$aHolzapfel, Gerhard 000015085 8560_ $$ffischerc@itam.cas.cz 000015085 8564_ $$s363353$$uhttps://invenio.itam.cas.cz/record/15085/files/TS.SM01-1.02.pdf$$yOriginal version of the author's contribution as presented on CD, page 1659, code TS.SM01-1.02 . 000015085 962__ $$r13812 000015085 980__ $$aPAPER
