The fracture energy release rate G∼C, which is the important parameter of ice pressure calculation model that is built on energy balance method, is the fracture mechanics performance of ice material. It is related with these factors such as ice material loading rate P•, which must be measured by experiment. It is the experimental method of fracture mechanics used in this paper. These ice specimens...
Referenced the fracture mechanics theories, based on the consideration of the destruction characteristics, the cementation force of ice in the ice and fictitious crack, the wing crack fracture model of base layer of reservoir Ice Layer. the fracture toughness, is the fracture mechanics performance of ice material, which must be measured by experiment It is the experimental method of fracture mechanics...
Referenced the fracture mechanics theories, based on the consideration of the destruction characteristics, the cementation force of ice in the frozen soil and fictitious crack, the wing crack fracture model of base layer of reservoir slope is proposed. The calculated results of finite element analysis agree with soil mechanics experimental results in terms of the soil mass of base layer of reservoir...
Based on the idea of the extended finite element method (XFEM), a new enriched displacement function, the exponent discontinuous function is presented to simulate the discontinuous character resulted from discontinuity such as crack, interface or joint. Simultaneously, for element containing the crack tip, the triangular basis function is introduced to embody singularity of the discontinuity tip....
