A thick-walled cylindrical pressure vessel as shown in Figure 2 is subjected to an internal pressure p, and has stress components: Pi 9(TT) == (zz) = 2, where Q = ( − 1). = Assume that the pressure vessel is made of steel with elastic modulus E = 200 GPa, Poisson's ratio v = 0.3, yield strength ovs 1000 MPa, inner radius a = 1.0 m, outer radius b = 1.2 m, and length L = 10 m. Calculate the pressure pi at first yielding using the von Mises and Tresca conditions. Calculate the change in the wall thickness and axial dimension L of the vessel at yielding.
