A study of the development of transient deformation in aluminum alloy W319 is presented. Rapid tension tests are performed to determine the mechanical response of W319 over a range of temperatures and strain rates. These results; as well as optimization analysis, are used to develop a thermomechanical constitutive model for W319. The constitutive model is implemented as a user material subroutine in ABAQUS, and beam quenching experiments are performed in order to verify the constitutive model. Beams with different cutout geometries are used in order to obtain experimental results for complex stress states and varying amounts of inelastic deformation. Residual stresses are measured using a groove removal technique upon completion of the quenching process. Results from these experiments compare well to the analytical results computed using the constitutive model.
