Prediction of Fracture Behavior of 20MnCr5 and S275JR Steel Based on Numerical Crack Driving Force Assessment
Two types of steel, 20MnCr5 and S275JR, are compared in this paper based on numerical prediction of their fracture behavior. The comparison was made using the numerically determined J-integral, an important fracture mechanics parameter. For that reason, a numerical algorithm that calculates the J-integral as a measure of crack driving force was developed. As an input, the algorithm uses results from the finite element analysis conducted on numerical models of two types of specimens usually used in experimental fracture investigations, single-edge notched bend (SENB) and disc compact type (DCT). The J-integral results obtained are plotted versus specimen crack growth size (Δa) for a range of specimens’ initial crack sizes (a/W=0.25, 0.5, 0.75).
