Streszczenie:

Scharakteryzowano kierunki badawcze w mechanice materiałów ciągliwych. Omówiono proces niszczenia metali związany z rozwojem pustek. Przedstawiono zarówno modele materiałowe opracowane w ostatnich latach, jak i będące rozwinięciem kryteriów klasycznych. Szczególną uwagę poświęcono modelowi materiału plastycznego Bai-Wierzbickiego, analizując jego podstawowe założenia. Zaprezentowano przykład wyników symulacji, wskazujący na przydatność proponowanego rozwiązania w analizie stalowych elementów konstrukcyjnych.




Abstract:

The paper discusses the latest trends in the mechanics of ductile materials. It analyses the process of metal failure resulting from void nucleation. The material models used in the study include the recent approaches as well as extensions of the classical criteria. Special attention was paid to the Bai and Wierzbicki model of a plastic material and its basic assumptions. Simulations were conducted to indicate the suitability of the proposed solution to assess the structural integrity of steel elements.
