| 摘 要： | 提出了一个基于常加速度常边界力广义Ｓｍｉｔｈ条件的非反射边界方法，并给出了相应的半无限域中动力问题的显式－隐式算法．数值算例表明，它具有与常速度常边界力广义Ｓｍｉｔｈ非反射边界方法相同的精度，但显著地节省了计算工作量和计算机的存赌要求，且便于程序实现。

| Abstract: | Non-reflecting boundary method based on the generalized Smith conditions with constant acceleration-constant force is presented. A corresponding explicit-implicit algorithm for dynamic analysis of the semi-infinite body is given. Using the present approach, a good agreement of solutions is obtained as compared with the generalized Smith non-reflecting boundary method with constant velocity-constant force condition. Moreover,it is easier to implement, the computational effort and the storage required are considerably saved. |
