| Abstract: | The strength and fracture mechanism of brittle meterials of the like of rock and concrete is studied in this paper. The fracture criterion of three-dimensional combined mode cracks is set up on the basis of yield criterion of the maximum separate displacement (MAXSD) and compared with the fracture experiment results of three-dimensional and Ⅰ, Ⅱ combined mode cracks of the concrete material. |
