Original abstract
The paper presents a complex material model which covers the elastic-plastic behavior, material deterioration and ductile fracture. The calibration of such model was conducted for Aluminum Alloy (AA) 2024-T351 using specimens with various geometries and loading which covers various stress states. The model was then applied to the simulations of tensile test of plates. The computations were carried out in Abaqus/Explicit using the user subroutine Vectorized User MATerial (VUMAT), where the crack initiation and subsequent propagation was realized using the element deletion technique. The results were compared to the experimental observation in the end.

Článek prezentuje komplexní model materiálu, který zahrnuje elasto-plastické chování, degradaci a tvárné porušování. Kalibrace takového modelu byla provedena na slitině hliníku 2024-T351 s použitím vzorků s různou geometrií a zatěžováním, které pokrývá různé napěťové stavy. Model byl posléze aplikován na simulace zkoušky tahem plechů. Výpočty byly provedeny v Abaqus/Explicit s využitím uživatelského podprogramu Vectorized User MATerial (VUMAT), kde iniciace trhliny a následné šíření byly realizovány pomocí techniky mazání prvků. Nakonec byly výsledky porovnány s experimentálním pozorováním.
