Explanation of Impact Resistance of Materials with the Help of Specific Energy Absorption Capability (SEAC)

Abstract

The impact resistance of materials is a significant criterion for material designs. The impact resistance can be tested in the areas of use of the materials as well as measured by impact tests in the laboratory environment. In this study, a test material was designed by placing 10 different materials, mainly alumina and steel ball, between two plates based on Al 5083. 10 J of energy was applied to one side of the designed test material with a drop-weight tester, and from the other side, the output forces were measured with a dynamometer. In the experiments, the input forces were measured using a drop-weight tester and the output forces were measured using a dynamometer placed on the back surface. To make the forces applied to the front of the material more stable, the impact tests were repeated under the same conditions by placing a polymer material on the front surface, and the tests were modeled using the abaqus program. The test results of the polymer and non-polymer design were compared with the numerical modeling results, and as a result of the study, the Specific Energy Absorption Capability (SEAC) model was created to explain the energy absorbtion ability of the materials.
