Plastic Deformation Waves and Heat Generated Near the Yield Point of Annealed Aluminum

  • Oscar W. DillonJr.


Experimental data on the propagation of deformation waves and the heat generated during the plastic deformation of annealed aluminum are presented. Particular emphasis is given to the transition from the elastic to the plastic state. Wave propagation data that are consistent with annealed aluminum being mechanically unstable under impact loading are given. Some wave propagation results for specimens made by gluing soft and hard sections together are included.

Experimental data on the heat generated in annealed aluminum tubes undergoing torsional oscillations at about one cycle per second are also presented.
