A thick-walled cylinder of mild steel with 250 mm internal diameter and 400 mm external diameter is subjected to a gradually increasing internal pressure P. 1. Using non-linear formulation, determine the value of P and sketch, giving significant stress values, the radial and tangential stress distributions when: The material of the cylinder first commences to yield. b. The cylinder material suffers complete plastic failure. a. II. Compare all the results obtained from part I (a, b) with those calculated when a linear stress distribution throughout the wall thickness is assumed. Also sketch the radial and tangential linear stress distributions, giving significant stress values. The yield strength of the material is 280 MPa. It is essential to provide clear drawings of the stress distributions as required.
