Utilization numerical methods for critical strain of tensile steel

Ladislav Novotný

Abstract


The possibilities of numerical simulations of void growth are described there using finite element method. Influences of used law of void growth on critical state are analyzed. Various shapes of specimens allowed various stress states, which enabled to verify applicability of used method.

Keywords


Crack, damage, failure load, finite element method, void growth.
