Abstract
Super plasticity is the capability of materials to parade very high tensile elongation which can be more than 2500%, appearing in eminent temperature under low stress dependent on strain rate. In this paper intentions to optimize superplastic parameters such as yield stress, ultimate stress, temperature, strain rate and strain rate sensitivity index by using hot tensile test method in AA 7075 alloy in experimental and numerical simulation method. In experimental method, the cross head velocity concept has been adopted to attain the permeability by achieving the material properties with the functions’ of temperatures conditions. Finite element method using ABAQUS software was modeled to compare the experimental results.
