In this study, dynamic punching shear tests of polyurea with different polyurea thickness were investigated using Applied Element Method (AEM) simulation. The simulation results were verified based on the experimental results. It was found in this study that a 3mm and a 10mm thick polyurea with 500mm x 500mm area could not withstand 758J and 3,983J impact energy, respectively. However, a 5mm thick polyurea could withstand 758J impact energy. Effectiveness of the polyurea sheet depended on impact energy, polyurea thickness, bond strength, and material properties of polyurea and primer. |
