Abstract

This paper presents an investigation of plastic de-formation of plates with holes made of plastic steels. Plas-tic deformation in plate hole edge area and fracture with appeared crack are studied. Specific fracture energy is cal-culated for strength and fracture evaluation which is ob-tained as a sum of fracture energy crack and deformation energy value with ultimate strength limit coherent with the parameter, describing stress concentration level. For the calculations strength and fracture parameters are used which were obtained during the experiment.
