Title Stress-Strain State and Stress Intensity Factors of an Inclined Elliptic Defect in a Plate under Biaxial Loading

Abstract We consider a mathematical model of the stress-strain state of a plate with an inclined elliptic defect. We obtain approximate formulas for the stress tensor, the displacements, and the principal stresses near the defect vertex. The obtained formulas are compared with the results obtained by the holographic photoelasticity method.
Keywords fracture mechanics, elliptic defect, stress tensor, biaxial loading, holographic interferometry method
