Abstract
A detailed experimental study of large amplitude plastic waves in annealed aluminum is presented. Using the author's diffraction grating technique, accurate strain-time and surface angle-time histories are obtained at different locations in the vicinity of impact. Verification of the strain-rate independent theory with strain amplitude modifications is provided in this region for impact velocities up to 63 ft/sec. Poisson's ratio is dynamically determined for strains up to 1.5%. Marked changes are observed in the propagation behavior above 1.06% strain, related to the abrupt increase of Poisson's ratio from ⅓. The maximum amplitude of waves above this value decreases exponentially with distance from impact.This publication has 3 references indexed in Scilit:
