Stresses in finite anisotropic plate weakened by rectangular hole

• Stress analysis of finite anisotropic plate with rectangular hole is carried out for in-plane loading.
• Stress functions are derived using complex variable and boundary collocation method.
• Effect of various parameters on stress distribution around the hole is studied.

In this paper, a solution to calculate the stress components around rectangular shaped cutout in a finite anisotropic plate subjected to in-plane loading is presented. The stress functions are derived using complex variable approach and least square boundary collocation method. The influence of plate size, material properties, stacking sequence, hole geometry and loading conditions on the stress concentration is also presented. Some of the results obtained by present method are compared with finite element solutions and with the existing literature.
