This paper describes a construction of a finite element model of a human finger for the use of estimation of laceration in jamming/crushing in living life. To accurately implement both the shapes of internal structures of an finger and the deformation characteristics, the shape of the model and deformation characteristics of the skin layer were obtained from an same specific individual. Moreover, hyperelastic characteristic of the skin layers were modeled with Ogden material model to accurately calculate the shear strain in large deformation. As the results of the application to simulations in case of jamming occurring in living life, the hyperelastic skin layer model was effective for the situations occurring large deformation of a skin layers.
