摘要
本文提出了考虑形状摄动时的边界元技术,它可以评价不确定形状结构的统计特性。为了证明本方法的有效性,列举了两个数值例题,计算结果表明,该方法完全可信。
A new boundary element technique is developed, which enables us to evaluate statistical behaviour of structures with uncertain shapes.The method is based on second order perturbation technique (SOPT). The formulation is verified through numerical examples of a disk or hole fluctuates in the frame of elastic, small displacement theory.
