Computational Damage Model for Thermoviscoelastic Laminated Composites, Third Phase: Model Parameters Development

Abstract

The present paper contains the model description for developing the damage parameters under the conditions of high rates of loading in impact experiments. The worked out methodology is illustrated on an example of processing the experimental results and spallation of organic materials to develop the critical dissipation energy. The results of the present investigations show that the dynamical wave pattern generated as a result of impact in the samples depends strongly on the damage parameters. Thus the entropy growth factors for the shear and tension as well as the breakup criterion - the critical value for the dissipation - could be developed. Those damage parameters for the organic glasses were developed based on an impact experiment.
