| 摘 要： | 简要介绍了花岗岩材料的动态压缩实验结果,同时建立了花岗岩材料的裂纹模型,并基于断裂力学以及纲以细观力学的相关理论,模拟了花岗岩材料的在动态压缩载荷作用下的强度特性,建立了花岗岩材料在单轴动荷载作用下的本构模型。这些模拟结果与实验结果相符。

| Abstract: | The experimental studies on the mechanical properties of a granite under dynamic compression are briefly introduced in the present paper. The crack model of rock material under dynamic compression is also established. Based on the fracture mechanics and mircromechanics, the simulated strength under dynamic compression, as well as the stress strain cures under dynamic uniaxial compression of the granite are obtained. It is indicated that the simulated results agree with the experimental results. |
