| 摘 要： | 提出了利用神经网络，根据应力集中处附近已知的三点应力（或应变值）来确定最大应用的一种方法，建立了一个３－４－１的网络结构，通过对网络的训练建立了应力集中处附近已知的三点应力（或应变值）与最大应力之间的关系，数值结果表明，提出的方法是有效，可靠的。

| Abstract: | A method is proposed to determine the maximum stress in terms of stresses (or strains) at three points nearby a region of stress concentration by using a neural network. The network structure with 3 4 1 is established and some data are collected to form training samples of the network. The relationship between the stresses (or strains) at the three points and the maximum stress of stress concentration point is gotten by training the network. Numerical results show that the method proposed is efficient and reliable. |
