摘要
采用相同的单边裂缝方形短柱和统一的分步加载方式,对混凝土进行了压缩Ⅰ型、Ⅱ型、Ⅲ型及压缩条件下的各种复合型断裂测试,给出了Ⅰ-Ⅱ-Ⅲ复合型临界断裂全曲面.
Specimens with same side cracks and the same loading method are used to test the stress intensity factor of model I and mixed model fracture for concrete under compression.The critical surface of ⅠⅡⅢ mixed models is given.
