| Abstract: |
| Based on fundamental principles of the VFIFE,the basic formulas of the 8-node hexahedral isoparametric element are firstly derived in this paper.Through the projection method,the space-curved hexahedron is converted to the space-flatted hexahedron.Then,the pure nodal deformation through reverse movement of the reference plane,and the internal nodal forces through virtual work equation of the element shape function.Effective approaches are also proposed for some key problems,including the coordinate modes and the integral modes for internal forces.On this basis,a computer program is developed and applied to the analysis of the engineering structural examples.Results show that,the static analysis,the dynamic analysis and the large deformation and large displacement analysis for solid structures can all be well performed by the developed program,verifying the correctness and practicability of the theory and the program. |
