Sažetak
The mechanical response of an infinite thin plate with a central line crack, which undergoes due to the applied remote biaxial loading plastic deformation in the neighbourhood of the crack tips, is considered in this paper. To describe the plastification process the Dugdale-Barenblatt yield model, which was originally used by Dugdale to solve a specific loading case in conjunction with the Tresca yield criterion, is utilized. Two yield criteria are considered, actually the ones attributed to Tresca and Mises. The analysis of the investigated mechanical response, which includes stresses and displacements, is based on its analytical determination using methods of complex analysis. At the end, the impact of the load biaxiality on the plastic yielding is discussed in view of the two considered yield criteria.
