dc.description.abstract於程式中可在有限空間生成不同形狀之顆粒,霣降、堆積後進行安息角試驗模擬,以 MATLAB 7.1 軟體作為後處理,可展現出顆粒在空間的運動狀況、分佈情況與剖面圖,以利分析。 孔隙比、顆粒間之接觸點數、顆粒形狀、顆粒基本摩擦角等堆積體有關參數,為影響顆粒狀材料力學行為之重要因素。本論文針對不同顆粒形狀與安息角的關係做研究,安息角試驗方式分為移除單一邊牆與單一邊牆斜傾90度兩種,依試驗分析結果得知,顆粒形狀確實會影響顆粒堆積體安息角之大小,且扁橢球的安息角最大,卵球次之,長橢球最小。zh_TW
dc.description.abstractThe domain to be filled with particles can be a polyhedron of any shape. Simulation results can be processed by MATLAB 7.1 to display the distribution of particles in space and the fabric structure at any instant. Parameter studies of the influence of the void ration, the contact numbers among the gravels, particle shape and the internal friction angle between particles on the macroscopic behaviors of particles assemblies are conducted in this thesis. In this study, it emphasizes the relationship between the angle of repose and the particle shape. The reactions of angle of repose are taken account by the relative particle shape through remove one side of wall and set a wall spinning slowly into 90 degree. It is found that the particle shape will influence the angle of repose, ellipsoidal particles are the most, and then egg-shaped particles and the long ellipsoidal particles are the least.en_US
