In fracture evaluation in regions other than head in forensic engineering, dummy skin that reproduces load of propagating human soft tissue has been used. However, conventional dummy skins often have narrow velocity range that can be applied in incident or accident, and are not used very often. Therefore, there is the need for dummy skin that can be used in wider velocity range. In this paper, we focused on super soft urethane resin (SSUR) which can be expected to be used as dummy skin in wider velocity range. Furthermore, regarding the load when external force was transmitted to bone, the effectiveness of SSUR was examined by comparing with soft tissue and conventional dummy skin. As a result, it was confirmed that SSUR can be used in wider velocity range than conventional dummy skin. In addition, since propagation load for impact velocity in SSUR was similar to that in soft tissue, it became clear that this could be used as dummy skin in various velocities. Furthermore, since the effect of thickness on propagating load in SSUR was similar to that in soft tissue, it became clear that it could be used as dummy skin for fracture evaluation in individuals and regions.
