Plastic deformation and damage evolution in low-carbon cast steel containing non-metallic inclusions are analyzed
experimentally and numerically. The cast steel was subjected to the heat treatment: normalizing, oil quenching and
tempering. Tests were carried out at hydrostatic pressure of 500 MPa and 1 000 MPa. In the tensile test the tensile
strength, elongation and reduction of area were examined. Fractography of the specimens was carried out to observe
fracture mechanisms. The finite elements method has been used for modelling of deformation of the specimens.
The computer simulation was performed using ABAQUS system. The computed output was compared with
experimental results
