摘要：

Mechanical properties of sheet materials are affected by the strain conditions. In this study, the influence of the strain rate on the mechanical properties of AA2139-T351 aluminium-alloy sheet materials was studied, by applying uniaxial tensile tests on these materials at four different strain rates (0.03, 0.003, 0.0003, 0.00003) s(-1). Upon analysing the obtained results, it was seen that the elongation, anisotropy value and the load-carrying ability during the necking were reduced, while the AA2139-T351 yield strength, tensile strength, work-hardening coefficient and work-hardening rate were not significantly affected by the increasing strain rate.
