QUESTION 3 Open with 3.1 A cylindrical pressure vessel of the internal radius R is subjected to the internal pressure P. Derive the relationship between the vessel wall thickness based on the Tresca criterion (t1) and the Distortion Energy criterion (t2). Assume all other conditions are the same. (6) 3.2 Sketch these criteria on one graph showing the corresponding points.

If the bar is subjected to two plane stresses the tension stress Ox =01 = 100 MPa and a 350 Compression compressive stress Oy =02. Ignoring the factor of safety, determine the 300 maximum allowable compressive stress Oz based on: 250 Tension a) The Maximum Normal stress criterion (1) 200 b) The Coulomb-Mohr criterion (3) 150 Stress (MPa) ab 100 50 0 0.2 0.4 0.6 0.8 % Strain (%) Page 26 + [12]
