In calculation, adopted load-unload criterion of stress wave propagation was to decide load-unload state of element and to adjusts and transfers internal stress for tensile failure element as well.
计算中用应力波传播的加卸载判别准则来决定单元的加卸载状态，对受拉破坏单元进行内部应力调整和应力转移。
Direct tensile, acceleration, and shock wave tests belong to the tensile test group, whereas adhesive tape, direct shear, peel and scratch tests belong to the shear test group.
直接拉离、加速和冲击波等方法属于拉力法，而胶带、直接剪切、剥离和划痕等方法属于剪切法。
A percussion device (7) gives impact pulses to a waveguide (21), where a compression stress wave and a reflected tensile stress wave are generated, which propagate in the waveguide.
冲击设备(7)向波导(21)提供撞击脉冲，在波导中产生压缩应力波和反射的拉伸应力波，应力波在波导中传播。
