%X Several specific numerical examples and analysis are made for complex multi-body system composed of rigid bodies,elastic bodies and elastoplastic bodies with applications of elastic and elastoplastic analysis methods of discontinuous deformation of multi-body system from different aspects. The effects of mechanics parameters of contact interfaces and strength parameters of materials on deformations,stresses and contact stresses,and plastic zone of these systems are studied. Very interesting results and comparatively reasonable conclusions are obtained. From examples it is showed that discontinuous deformation computational mechanics model is a new and powerful method of numerical analysis and simulation,and may process numerical analysis and simulation of static,dynamic and coupled nonlinearities of contact and materials for general complex multi-body system composed of rigid bodies,elastic bodies and elastoplastic bodies,with wide-range application foreground.
