Static and dynamic deformation test results were obtained for AI-Mg alloy 5086 material in various conditions in order to provide a constitutive equation for use in code computations of more complex explosive deformations. Conventional laboratory tensile tests showed interference of a reversed strain rate effect because of dynamic strain aging (DSA). The DSA behavior was confirmed for additional material conditions spanning the mechanical and thermal H32 processing treatment of as-supplied pipe stock. Influences of grain size acid H32 treatment on yielding and subsequent strain hardening behaviors were evaluated. Split-Hopkinson pressure bar test results on related AI-Mg alloy 5083 material were employed in the determination of applicable constants in Zerilli-Armstrong (Z-A) constitutive equations. Use of the equations is reported here for description of shock-induced bulging of a water-filled pipe material in hydrocode validation tests.
