The deformation, stress relaxation, stress recovery, creep rupture, creep buckling, and creep ratchetting aspects of creep are discussed with the emphasis on deformation of a plastic due to a tensile load. Two problems were run using the ABAQUS Finite Element Program: an axisymmetric steel pressure vessel with elliptical end caps, and a plastic rectangular beam in tension. The pressure vessel model was used to check the ABAQUS program against the literature. A graphical comparison of the stress results showed that the program showed the proper relationships and magnitudes to confirm agreement The plastic rectangular beam problem showed an error less than 10% in total deflection and negligible error in the stress calculations.
