Abstract:The steady state impressing velocity of the punch during an impression creep test is calculated by the finite element method based on a single power law constitutive equation for the deformation of each and every element. The calculated impressing velocities and their stress dependence agree very well with the experimental values on succinonitrile crystals using empirical power laws obtained from unidirectional creep tests.
