基于神经网络算法的应力集中值的确定法

STRESS CONCENTRATION PREDICTION BASED ON NEURAL NETWORK METHOD

摘要: 基于神经网络的B-P算法，根据应力集中附近的三点应变值，通过网络训练，建立了应力集中附近的三点应变值与最大应变值之间的映射关系，从而方便地确定最大应变值.结果表明，该方法使用方便，预测精度高，结果可靠.

Abstract: Based on B-P neural network method,the relationshipbetween the strain at the three points and the maximum strain in theregion of stress concentration is obtained by training the network.The maximum strain can be obtained easily. Analysis shows that the methodis efficient and reliable.
