Analisys of stress state in a plane anisotropic field weakened by a circular hole

Abstract

It is the fact that mechanical parts with holes are often encountered in practice. A know ledge of stress distribution is of paramount importance for engineering practice. Therefore, the objective of this paper analyzes the impact of the circular hole as a source of stress concentration on the stress state of uniaxial strained orthotropic plate since the practice has shown that the largest number of structures is weakened by the hole shape. In this paper for obtaining the results of stress distribution in a plane anisotropic field weakened by a circular hole, numerical method was used. The methodology was applied enabling the determination of the values of the stress at each point of plate, as well as at points at the hole contour, which is based on the application of the basic equations of the theory of elasticity
