Abstract: In order to improve the office paperfeeder design and minimize paper jam fault in running office equipment, paper mechanical properties are studied by means of nonlinear finite element method. Based on the updated Lagrangian description, the incremental equilibrium equations of triangular plate-shell elements for geometrically nonlinear problem are derived. The paper static deformation and dynamic response (without damping) due to gravity loading are analyzed. The calculated results accord well with those obtained by experiments and are more accurate than those by international commerical software MARC.
