Strength of Elastoplastic Plates Containing Square Holes (Inclusions) and Cuts (Thin Inclusions) Under Uniaxial Tension

摘要

We study the influence of stress concentrators (square hole, cut, or perfectly rigid inclusion) in a plate on its strength under uniaxial tension with the help of the numerical solution of boundary-value problems of the theory of small elastoplastic deformations for a linearly hardened material with regard for its unloading.
