combining boundary element method (bem) with the perturbation theory, this paper presents a perturbation method based on bem for shape design sensitivity analysis of elastic structures.
本文将边界元方法与摄动法相结合,提出了计算结构响应对其形状改变的灵敏度的边界元摄动法。
based on the material derivative approach and the direct differentiation method (ddm), the reproducing kernel particle method (rkpm) is developed further for shape design sensitivity analysis (dsa).
