The Mechanical Response of a Porous Uranium Alloy.
Abstract
Experimental and theoretical results are presented for the mechanical response of a porous uranium alloy subject to quasistatic uniaxial strain and hydrostatic compression. Two states of porosity were studied; one very small (about 1%) and the other somewhat larger (about 13%). Experimental techniques previously employed on geological materials are used to obtain all principal stress and strain components. Also, longitudinal elastic wave speeds obtained by ultrasonic techniques are presented as a function of initial sample density. The stress-strain behavior of this material is porosity dependent and no distinct elastic limit or crushup strength is observed. An analytical model that considers both the mean normal stress and the deviatoric stress influence on the crushup process is developed for uniaxial-strain and hydrostatic loading conditions.
