Abstract: This paper discussed a
elastic/viscoplastic material according with Bridgman hypothesis and condition of
simply loading, and linearizated its nonlinear constitutive equations by means of three
parameters of orthogonal transformation¦Òm ,¦Ì¦Ò£¬j¡ä£²ª§.
Laplace transformation is suitable to solve the basic equations of three dimension of
Viscoplastic problems, including the separameters. A few typical problems of
elastic/viscoplastic mechanics was analyzed by the method.
Keywords: elastic/viscoplastic, constitutive equation, Laplace
transformation.
