弹性模量

In this thesis, the crystal structure and phase transition behaviors of a andβforsterite (Mg2SiO4) at high temperature and high pressure were investigated by the first principle calculations and the quasi-harmonic Debye model. Variations of elastic properties, band structure, density of state, band gap ofαandβforsterite with pressure were calculated, and the effect ofα/βphase transition on these characters was analyzed. The effects of water on elastic modulus, sound velocity and band gap of forsterite were also simulated. Finally, the effect ofα/βphase transition and water on seismic discontinuity in earth was discussed.

In this paper, material properties of the segment of the porous metal-bonded diamond grinding wheel were researched by finite element simulation. Segments were manufactured according to the design result and their elastic modulus was measured. The key points are as follows: The influence of the porosity on the elastic modulus was analyzed through a finite element method. In the FEM model, the design variable only includes the porosity, and the tetrakaidecahedron model is applied as the microstructure model of porous metal matrix. The corresponding porosity was decided in order to meet the requirement of the elastic modulus.
