    　View Summary

    This paper aims to fabricate a composite material using calcareous waste concrete powder and coal fly ash (FA) by spark plasma sintering. The effect of FA addition on the mechanical properties of the composite material were investigated. The maximum FA content was 7.5 wt%. The relative density of the composite material was approximately 1.0, independent of FA content. In contrast, the Vickers hardness, flexural strength, and flexural modulus increased with increasing FA content. However, the dispersion state of FA in the composite material was not observed by scanning electron microscopy. Powder X-ray diffraction of the composite material revealed that spurrite and wollastonite were formed identically, independent of FA content. Therefore, FA serves as a reinforcement in the composite material.

  • Performance evaluation of three-node triangular element based on generalized finite element method approximation for nearly incompressible materials

    KIMURA Koshi, KANDA Yasuyuki

    　View Summary

    Rigid plastic and large deformation analyses of the finite element method (FEM) require multiple remeshing procedures to avoid a decrease in the analysis accuracy. Thus, a three-node triangular element that can perform automatic mesh generation is suitable for these FEM analyses. However, in the FEM analysis of nearly incompressible materials using the displacement-based three-node triangular element, the inhibition of volumetric locking and pressure checkerboarding is required. The generalized finite element method (GFEM) approximation can improve the analysis accuracy for three-node triangular elements without the addition of midpoint nodes. In this study, we performed a detailed performance evaluation of a three-node triangular element based on the GFEM approximation for nearly incompressible materials in the linear elastic analysis. The GFEM approximation employs a polynomial of degree 1–3. Performance investigation using a compression test revealed that each GFEM element required the application of selective reduced integration to avoid volumetric locking and pressure checkerboarding. Furthermore, we investigated the number of constraint degrees of freedom of the GFEM element, which is related to volumetric locking. In the case of the GFEM element, we inferred that the application of this investigation is difficult because of the additional nodal degrees of freedom, which are different from the translational nodal displacement.
