Systematic study is done for the strain energy density factor criterion, distortional strain energy density factor criterion, dilatational strain energy density factor criterion, circumferential tensile stress criterion, energy release rate criterion and twin shear stress criterion
對應變能密度因子準則、形狀改變能密度因子準則、體積改變能密度因子準則、能量釋放率準則以及最大周向拉應力準則和雙剪應力準則進行了系統地研究。 -
At first, ploygon aggregate structure of concrete is randomly generated in two - dimensional plane with monte carlo method on the meso - level. then, the growth process of a crack of concrete 3 - point bending beam specimen is analyzed by fem, according to the criterion of maximum circumferential tensile stress. and the path of crack to spread in mortar, aggregate and interfaces of them is gained by the ultimate fracture criteria in construction standard that the width of crack should not be more than 0. 2mm
首先，在細觀層次上，根據蒙特卡羅隨機抽樣原理，在二維平面上建立了混凝土多邊形隨機骨料結構模型，然後採用有限元計算方法，根據最大周向正應力準則，對三點彎曲梁構件進行了開裂過程的模擬，並以建築規范中構件裂縫小於0 . 2mm的要求為最終破壞標準，得出了裂紋在基質、骨料及界面的擴展路徑。
