Zaprezentowano wybrane wyniki analizy numerycznej płyt CCSP(BT) z centralnym pęknięciem poddawanych dwuosiowemu rozciąganiu. Przedstawiono szczegóły modelu numerycznego, wpływ poziomu dwuosiowości naprężeń rozciągających płytę na wartość całki J oraz rozkład naprężeń przed wierzchołkiem pęknięcia. Analizę prowadzono z założeniem małych i dużych odkształceń.

Presented are selected results of numerical analysis for CCSP(BT) plates, containing a central crack subjected to biaxial tension. Details of the numerical analysis were presented and the discussion about the impact of the level of biaxial tension ratio on stress field near crack tip was done. The analysis was performed on the assumption of small and large deformations.
