摘要：

Generalized node with generalized free of degree, mathematical cover and physical cover were presented. The mathematical cover is constituted of generalized nodes, and different types of mathematic cover were introduced. Generalized finite element is composed of mathematical cover and physical cover and constitutional relation. Different characteristic mathematical cover and constitutional relation form different characteristic generalized finite element to simulate different characteristic bodies in multi-body system of interaction, such as rigid body, elastic body, elasto-plastic body, viscoelastic body and viscoelastoplastic body. The fundamental matrixes and vectors of general generalized finite element were given out. Solid foundation was established for discontinuous-deformation-computational-mechanics model on the hand of element discretization.
