岩体的震动或爆炸荷载导致了瞬时荷载的产生，而由此产生的应力状态将是动态的或准静态的。
Rock vibration or explosion load lead to the instantaneous load, under these circumstances, stress is at dynamic or quasi-static.
为了减少计算时间，采取了提高准静态加载速度的方法。
To reduce the computational time, the speed of quasi-static loading is increased.
得出了在不同拉伸速度和边框长度条件下装置处于准静态时的临界剪切角，并且分析了织物试样尺寸大小对准静态范围的影响。
The critical shear Angle of quasi-static state was given under different loading speeds and frame lengths condition, and the influence of specimen size on this shear Angle range is also discussed.
