Abstract EN
Based on the model of rigid-spring element suitable for homogeneous elastic problem, which was developed by Japanese professor Kawai, the interface stress element model (ISEM) for solving the problem of discontinuous media mechanics has been established.
Compared with the traditional finite element method (FEM), the ISEM is more accurate and applicable.
But the total number of freedom degree of ISEM in dealing with three-dimensional problems is higher than that of FEM, which often brings about the reduction on efficiency of calculation.
Therefore, it is necessary to establish a mixed model by gathering the advantages of ISEM and FEM together.
By making use of the good compatibility of ISEM and introducing the concept of transitional interface element, this paper combines ISEM and FEM and proposes a mixed model of ISEM-FEM which can solve, to a large extent, the contradictions between accuracy and efficiency of calculation.
In addition, using natural coordinate, algorithm of ISEM for block elements of arbitrary shape has been performed.
Numerical examples show that the method proposed in this paper is feasible and its accuracy is satisfactory.
