Dynamic Response of Metal-Polymer Bilayers - Viscoelasticity, Adhesion and Failure

Abstract

A series of fundamental experiments have been performed on the onset of localization under dynamic loading in tubular specimens of bare and polymer coated Al 6061-O. These experiments reveal that the onset of shear banding localization is unaffected by strain rate effects, but influenced by statistical distribution of flaws; the effect of the coating is shown to be inertial. High strain rate response of rubbers and elastomers is also examined using transient wave propagation experiments at strain rates in the range of 1000 to 10,000 per second. The potential for cathodic delamination of polyurea from steel was also considered.
