An aluminium pressure vessel (radius/thickness=20) is closed at each end and pressurised to 7 MPa to cause plastic deformation. Neglect the elastic strain and find the plastic strain in the circumferential (hoop) direction of the tube. The plastic stress-strain curve is given by o=17080.25 MPa, where stress is in MPa. Assume thin- walled tube in this scenario, the stresses on the outside of the tube are circumferential stress, σe = pr longitudinal stress, O₂=2, and radial stress, σ, = 0. 1
