导出了任意形状泛函的三维弹性拓扑导数的形式。在所谓的气泡法框架下，TD用于结构力学中形状优化问题的数值求解，以及形状逆问题的数值求解。*由蔡国强传讯。
The form of topological derivative (TD) in three-dimensional (3D) elasticity is derived for an arbitrary shape functional. TD is used for numerical solution of shape optimization problems in structural mechanics in the framework of the so-called bubble method, as well as for numerical solution of shape inverse problems. * Communicated by K.K.
