To investigate the deformation characteristics of a crystalline polymer, creep tests under tension, torsion and combination stress conditions were carried out after the cyclic prestrain of tension and unproportional circle using POM. It was shown that (1) after a tensional cyclic prestrain the deformation resistance of creep is decreased in the prestrain direction, and is increased in other directions; (2) after a cyclic circular prestrain, creep deformation resistance in combination stress direction (θ=45゜) is increased, while creep deformation resistances in both directions of tension and torsion are decreased; and (3) strain course in successive creep How direction (θ=45゜) is always developed along the load direction (θ=45゜) in the cases with and without prestrain, independent of the prestrain history.
