内容記述 | Present paper consists of peak strength model and failure process simulation of both experimental and numerical method. The peak strength model of brittle materials with a pre-existing open-hole defect is proposed in this paper. A modified Sammis-Ashby model is deduced, which can be used to calculate the peak strength of brittle materials. It shows the law between peak strength σ.and independent variable μ, which is the ratio of open-hole radius (a) to half-width of the specimen (t). Then in the second part, both of experimental and numerical investigations were carried on open-hole specimens. A progressive elastic damage method (RFPA) is employed to inspect and verify the modified model and simulation the failure process. The investigation finds that there are good correlations between the experimental and numerical values. In the process simulation, due to the influences of boundary conditions, secondary cracks developed in the shear zones till failure, therefore the shear failure type was obtained. | |||||
