A general modified constitutive model of gradient and viscosity dependent is proposed based on kinematics description by Lagrange; and specified one can be gotten from an elastoplastic constitutive model in infinitesimal theory that is verified. Such a way to deal with the contribution by strain gradient and viscosity utilizes mostly the results of constitutive model research. And an analysis model of square intersection with unit sides
infinite in its length
and under infinitesimal description is adopted here to discuss the characteristic scale in perfect yielding material by parameters of the constitutive model under P wave inputting.
