Evaluation of T-stress for a hypocycloid hole in an infinite plate

Abstract

Purpose

This paper is devoted to the evaluation of the T-stress for a hypocycloid hole in an infinite plate. The remote tractions are applied for the infinite plate containing the hypocycloid hole. After using the conformal mapping, an elasticity solution is obtained, and the T-stress at the cusp tip can be abstracted from this solution. The paper aims to discuss these issues.

Design/methodology/approach

Conformal mapping technique is used for solving the T-stress problem for a hypocycloid cusp hole problem.

Findings

The present study proves that the cusp configuration has a significant influence to the value of T-stress at cusp crack tip.

Originality/value

A closed form solution for the T-stress in cusp crack is first obtained in the submission.
