It is important to estimate dimensions of large deformation and stress for flexible material in order to develop highly reliable sheet handling devices. In this paper, a spring-mass beam model is introduced to evaluate deformation behavior of the sheet. This model consists of rotational springs, shear springs and masses. First, the beam model for large deformation of the sheet is presented. Then the calculation results of the deformation configuration and acting force the spring-mass beam model are compared with the theoretical and experimental results. It is concluded that the simulation using the beam model proposed here gives good agreement with experimental results.
