  　View Summary

  In this study, we investigate the accuracy of four-node tetrahedral elements with drilling and strain degrees of freedom (GNTet4) for nearly incompressible materials. GNTet4 is a one of the generalized finite element method approximation. Three types of GNTet4 are introduced by applying approximation polynomials of the Taylor expansion. First, we reveal the extra degrees of freedom constraints without the zero-energy modes of each GNTet4 through eigenvalue analysis. Next, the displacement accuracy of each GNTet4 is evaluated by analyzing a cantilever beam. The results shows that GNTet4, which approximates the third-order Taylor expansion (GNTet4-3rd), is almost identical to a 20-node tetrahedral element. Furthermore, a plane-strain compression test is performed to investigate the analytical accuracy of each GNTet4 for nearly incompressible materials. To analyze nearly incompressible materials with high accuracy, selective reduced integration (SRI) and third-order Taylor expansion must be applied to GNTet4 (GNTet4-3rd with SRI). Incidentally, the analysis accuracy of GNTet4-3rd with SRI is the same as or higher than that of the 10-node tetrahedral element (FEM-Tet10). Furthermore, the GNT4-3rd with SRI, which possess the nodal point at the element vertex only, suppressed the nodal oscillation. Thus, in nearly incompressible materials, to obtain the same analysis accuracy as that of FEM-Tet10, the four-node tetrahedral element must apply the displacement function of the fourth order and the SRI.

• Development of second-order three-node triangular element with drilling and strain degrees of freedom

  　View Summary

  In this study, a second-order three-node triangular element with drilling and strain degrees of freedom (DOF) (GNTri3-2nd) was developed. GNTri3-2nd was formulated by applying an approximation of the generalized finite element method and a second-order Taylor expansion. The boundary conditions of the extra nodal DOF (drilling, normal strain, and curvature) without the zero-energy mode are discussed through eigenvalue analysis. The analysis accuracy of GNTri3-2nd was higher than that of the conventional six-node triangular element (FEM-Tri6) for the cantilever problem. Furthermore, in the case of plane-strain compression with a nearly incompressible material, the analysis performance of GNTri3-2nd was almost identical to that of FEM-Tri6 when a selective reduced integration was applied to the element stiffness matrix. Finally, we applied the GNTri3-2nd to the fundamental rigid-plastic finite element method. The analysis result of GNTri3-2nd is in good agreement with the slip line method and the conventional four-node quadrilateral element.
