The results show that brittle fracture occurs in matrix and the P-WCMOD(crack mouth opening displacement) curve is linear till loading to failure.
实验结果表明:水泥基体发生脆性断裂,从加载到试件破坏P-WCMOD曲线一直呈线性;
For crack-opening displacement tests, a specimen is notched and then fatigued by flexing to obtain a fine crack. Force is then applied until the crack begins to grow.
在裂纹扩展试验中,试样切口后使其弯曲并产生微小裂纹,在试件上继续加力直到裂纹扩大为止。
