Crack Growth Simulation with a Finite Element Method

The analysis of stress deformation aroud peak of the crack in plate with the opening was done in this work. Modeling and discretization of the analysed model was made by means of CASCA interactive program developed especially for modelling and discretization of 2D model. Program FRNAC2D/L was used for numeric analysis and results survey. In the analysis of stress condition in vicinity of the crack one start from the assumption of linear elasticity theory where plastification effect is also included. It is assumed that the analysed plate has only one crack with one plastic zone at the peak of the crack. The received results have been compared with results from literature.
