COMPLEX FUNCTION METHOD OF ANALYSING ELASTOPLASTIC STRESS CONCENTRATION PROBLEM WITH CIRCULAR HOLE SUBJECTED TO INTERNAL PRESSURE AND SHEAR

In this paper, complex function method and conformal transformation are used to analyse elastioplastic stress concentration problem with circular hole subjected to internal pressure and shear. The method employing complex function to find plastic stresses is further developed. The stress concentration function and the demarcation lines between elastic regions and plastic regions are given under complex loading conditions.
