【Abstract】 Based on penalty method,a 3 D finite element formulatiom for contact impact problems is proposed.In order to get the formulation,a bilinear interpolation is used to distribute the contact parameter. Numerical examples are analyzed to show the effectiveness of the method,and it is used to analyze dynamic response of the structure.更多还原
