论文摘要
Dieterich-Ruina速率和状态摩擦模型被转移到散装变体中，并且在这里也将影响耗散机制的状态变量（老化）与标准影响弹性响应的损害结合在一起。由于衰老具有单独的动力学，因此总体模型没有标准的变分结构。就稳态存在，原始核心的定位及其时间响应而言，研究了一维模型。具有无损害变体的计算实验表明粘性滑移行为（即构造断层的地震循环）以及在非常大的速度下稳定的滑移。
The Dieterich-Ruina rate-and-state friction model is transferred to a bulk variant and the state variable (aging) influencing the dissipation mechanism is here combined also with a damage influencing standardly the elastic response. As the aging has a separate dynamics, the overall model does not have a standard variational structure. A one-dimensional model is investigated as far as the steady-state existence, localization of the ataclastic core, and its time response, too. Computational experiments with a damage-free variant show stick-slip behavior (i.e. seismic cycles of tectonic faults) as well as stable slip under very large velocities.
