我们进行了数值模拟的自发动态断裂控制的滑移弱化法律沿着双材料界面（故障）与非故障的库仑塑性屈服形式的损伤。断层外塑性屈服稳定了褶皱状滑移脉冲，滑移速度增长率降低。在不同的模型参数下，断层上的破裂是双向的，而断层外塑性应变在两个破裂方向之间的分布是高度不对称的。
We perform numerical simulations of spontaneous dynamic rupture governed by a slip‐weakening law along a bimaterial interface (fault) with off‐fault damage in the form of Coulomb plastic yielding. Off‐fault plastic yielding stabilizes the wrinkle‐like slip pulse in terms of a decreasing rate of slip velocity growth. With a variety of model parameters, ruptures on the fault are bilateral, while off‐fault plastic strain distribution between the two rupture directions is highly asymmetric.
