Skin laceration accidents caused by the penetration of curvature edge frequently occur in daily life. However, little attention to skin laceration was paid due to minor injury, thus only few studies regarding the prevention and mitigation of skin laceration can be found. Considering that a fundamental study on skin laceration mechanism and threshold is necessary, in this study, drop weight penetration test device was developed in order to simulate skin laceration accident. The device was then used for evaluating the dynamic responses of skin simulant against several blades with different tip curvature radii. As a result, load and penetration depth at rupture increased with the increase of tip curvature radius of the blades. In addition, drop weight test result showed larger responses compared to quasi-static test result which might be due to the viscous effect and polymer characteristics such as cross-linking.
