1263 3DDEMを用いたコンクリートブロックの破壊挙動の解析(G03-11 材料力学(11)疲労・強度4,21世紀地球環境革命の機械工学:人・マイクロナノ・エネルギー・環境)
詳細
It is difficult to analyze theoretically the dynamic fracture of Concrete Block because it is discontinuous fracture behavior. In this research, the impact fracture when the impact body collides with the concrete Blocks is analyzed by using the Distinct Element Method (DEM). DEM is suitable for the analysis of the fracture behavior from the continuous body to discontinuous body. By this research, It clarified how destruction is caused in changing the condition of impact body size, impact body speed and impact body mass.
