In this paper, inelastic deformation behavior of A7075 Aluminum alloy under tensile loading was experimentally investigated at various temperatures and strain rates. The constitutive equations were developed in the range from 0℃ to 120℃ on the basis of the Two-Factors overstress constitutive concept considering aging as well as viscosity. These equations are very useful for analysis of dynamic deformation of structures like automobiles and airplanes, and also can express relaxation behavior.
