摘要：

A new method has been developed which allows the reduction of localized notch stresses in two-dimensional (2D) and three-dimensional (3D) elastic structures in a very effective way, with only a commercial finite-element code (the authors used ABAQUS) required. The method simulates on a computer the mechanism of tree growth copying the self-optimization of living trees which always try to grow into a shape of constant surface stress. The success and efficiency of the method is demonstrated by 2D and 3D examples. © 1990.
