1 INVESTIGATION OF THE EFFECT OF PLATE DIMENSIONS AND THICKNESSES ON THE IMPACT EFFECT OF A STEEL BALL

In this study, impact effect of a ball is investigated on different dimensions of plate geometries by using computational impact analysis. All modelling and solution steps are done by ANSYS LS-DYNA package software. A plate is fixed from its side locations and a steel ball is thrown towards plate. Standard steel properties are used in material properties determination. Kinematic hardening plasticity model is selected for investigating the plasticity behaviour of ball and plates. Increasing the speed and decreasing the thickness of the ball cause to increase stresses. The highest elastic strains occur in the results of the biggest ball diameter test. Less stresses and more stable results are taken with increasing the thickness of plate. Plastic deformations occur only in the impact tests of the highest ball diameter and the lowest thickness of plate results
