Standard test method for shear properties of composite materials by the v - notched beam method 用v形切口梁法測定復合材料剪切性能的標準試驗方法
Standard test method for shear properties of composite materials by v - notched rail shear method 用v型切口梁剪切試驗測定復合材料剪切特性的標準試驗方法
In this paper the introduction of the use cohesive element in concrete structure is given , and a kind of 2 - d isoperimetric cohesive element is deduced . the fracture process of concrete notch beam is calculated by fortran programming . the result shows that the method is feasible 本文主要對內聚模型在混凝土斷裂數值模擬中的應用做了一些討論,并推導出了一種簡單的二維六結點等參內聚單元,并用fortran語言編寫了含有內聚單元的有限元程序對混凝土切口梁的斷裂過程進行了計算。
