IDENTIFICATION OF MATERIAL MODEL PARAMETERS BY DESIGN-EXPERIMENTAL METHOD USING ANSYS AND LS-DYNA PACKS
LS-DYNA software is using long time for deciding the problems of punching the metal plates by high velocity objects. Herewith needs are appeared for determination of plastic characteristics of these material under high velocity loading. It is offered identification of elastoplastic model of material to conduct by the theoretical – experimental method. As the main limitations on an experimental procedure are followings: the experiment should be simple enough and highly quantitative. As such experiment there can be used an impact of a high hardness sphere with known initial velocity on a plate from an investigated material.
