In this paper, analytical and numerical simulations of the crack-tip stresses are presented. Analytical calculations are performed utilizing modified Rice and elastic equations. 2D finite element analyses (FEA) are conducted in parallel using ANSYS. Results from both methods are compared and discuss

Fracture toughness tests have been carried out on two different heat-treated steels 60Si2MnA using both through-cracked specimens with different a/W ratios and semi-elliptical cracked ones with variable crack size and shape. Effects of crack depth and shape on fracture toughness have been studied. R

An experimental study described in this paper attempts to compare the behaviour of both through-cracked specimens with different a/w ratios and surface-cracked test pieces. Results show that the material is more resistant to crack growth when the a/Wratios are less than 0.1, both shallow throughand
