Treść
The paper presents identifying studies of mechanical properties of the selected materials from the group of elastomers including Asmathane (65 ShA), Easyprene FPS (30 ShA), Biresin (U1305). The tests were carried out at the Laboratory of Strength of Materials, the Department of Mechanics and Applied Computer Science, with the use of an especially designed stand for testing the energy absorption of materials. The research aims were to determine the basic properties and characteristics of the selected materials as well as to compare them and identify the material with the best energy-absorbing characteristics. For a single load-unload cycle, applied dynamically, the hysteresis loops were recorded. Energy-absorption of individual materials and maximum strength were determined. During the experimental test, a fast speed camera was used to accurately register the progress performance of the test. The pictures of the dynamic tests of materials behavior are shown. The curves of the tested materials are compared in the graphs. The resulting data will help to create constitutive models of the tested materials which in the next stages of the project will be used in numerical studies on the impact of detonation on the designed protective panel.
