【Abstract】 It is known that the characteristic curves of aluminium materials with different grades conform to the same type function. Taking 6082 aluminum alloy as the research object,the tensile test was carried out based on room temperature constant velocity method. By analyzing the experimental data,the universal function of stress strain relationship of the aluminum material was obtained,and the material properties parallel to the fiber direction and perpendicular to the fiber direction were compared.更多还原
