Abstract : By using the true-stress true-strain relation, a simple finite-strain incompressible analytical solution technique is developed to predict pressure deformation relations up to the failure of thick-walled cylinders subjected to internal pressure. The material is assumed to be an isotropic hardening material that obeys the von Mises yield condition. The flow law for the material incorporates the Prandtl-Reuss stress-strain relations and a loading function represented by the true-stress versus true-strain diagram. Poisson's ratio is assumed to be equal to one-half for both elastic and plastic strains. The bursting pressure for thick-walled cylinders made of either SAE 1045 steel or copper is presented graphically for various ratios of outer and inner radii of undeformed cylinders. The true location of inner surface of cylinders made of both metals at various pressure levels was determined and presented graphically. Pressure expansion curves for cylinders made of SAE 1045 steel and OFHC copper are presented. (Author)
