| 英文摘要 |
The objective of this project is to develop the spontaneous rupture process of an interesting fault, and the anti-plane problem for a shear crack will be considered first in this year. The hyper-singular boundary element method(HBEM) in time domain was used to determine the crack opening under a specified stress drop then, the slip-weakening model will be adopted to define the linear constitutive law between the stress drop and the crack opening within the cohesive zone. In addition, the iteration process that is based on the dynamic stress intensity factor was developed and consequently, the spontaneous rupture process can be achieved to determine the dynamic slip function of cracks. |
