Sažetak
Numerical modelling and simulations were carried out in order to analyse fracture mechanisms for plates, damaged by a single and multiple cracks, and subjected to lateral pressure. For that purpose finite element models for plate specimens were developed using shell elements. Material property data used in the simulation were obtained from the tensile test and fracture test on a centrally notched tension specimen. By implementing elastic plastic fracture mechanics concepts (EPFM) critical pressures associated with fracture onset in the specimens were assessed based on the critical J-integral and CTOD parameters. Simulated critical pressure loads for panel specimens were compared with experimental results and a good agreement was observed.
