摘　　要：利用区域分解技术把弹性静力学问题转化为若干个子问题,采用伪谱方法并行求解每个子问题.该方法继承了伪谱方法易于编程、精度高的优点,且通过区域分解方法实现并行计算达到了优化计算时间的效果.数值算例说明了该方法的有效性.In this paper a pseudo spectral domain decomposition method for elastostatic problem is attempted. Under domain decomposition technique, the original problem is transformed to several sub-problems, which are solved in parallel by pseudo spectral method. This method maintains the advantage of easy programming and high accuracy of pseudo spectral method, and by using domain decomposition method for parallel computing, it optimizes the compu- tation time. Two numerical examples confirm the effectiveness of this method.
