Nonsmooth dynamic analysis of rigid-flexible interaction collision
《Applied Mathematics and Mechanics(English Edition)》2022年第11期1731-1746,共16页Ling TAO Zhongpan LI Yan LI Huijian CHEN Zhiqiang FENG 
supported by the National Youth Science Foundation of China(No.12002290);the National Natural Science Foundation of China(No.11772274)。
This paper aims to explore the deformation of the collided bodies in multibody systems and to effectively simulate the motion path of colliding bodies.First,we describe the geometrically nonlinear problems of material...
