| Outline of Final Research Achievements |
In this study, in order to determine the mechanical conditions for skin laceration and to establish a proper assessment method, experiments using skin simulant and porcine skin, as well as numerical analysis using skin finite element model were conducted. It is found that maximum strain value at the surface of skin simulant strongly correlated with the increase of rupture load. Moreover, risk curves that indicate the occurence probability of skin laceration could be obtained by statistically analyzing the experimental result of porcine skin. In addition, from the numerical analysis result, maximum principal strain at contact surface was considered to be a good predictor of skin laceration.
