摘要：

The problem of determining a stress-strain state described by singular and regular terms and a stress intensity factor in the vicinity of the tip of a crack-like defect in a plate under biaxial loading is considered. The Kolosov-Muskhelishvili method is used to obtain expressions for the stress tensor near the vertex of an ellipse, which yield formulas for stresses in the case of blunt cracks. The maximum shear stress, principal stresses, and stress intensity are determined. Formulas for the stress intensity factor under biaxial loading of a plate with a crack-like defect are obtained and can be used in the holographic interferometry method.
