The constitutive relationships of elastic / viscoplastic materials are discussed theoretically over a wide range of stress, temperature and plastic strain rates. Linear constitutive relationships between stress, the reciprocal of absolute temperature and the logarithm of plastic strain rate is assumed in any field of the above mentioned variables. The boundaries separating the various fields appear as straight lines, and two types of constitutive relationships bending convexly or concavely at the boundaries appear. These results explain the experimental results well. The mathematical model which explains them is presented.
