| Summary: | The aim of this study is to develop an elastic modulus predictive model during unloading of plastically prestrained SPCC
sheet steel. The model was developed using the back propagation neural networks (BPNN) based on the experimental
tension unloading data. The method involves selecting the architecture, network parameters, training algorithm, and model
validation. A comparison is carried out of the performance of BPNN and nonlinear regression methods. Results show the
BPNN method can more accurately predict the elastic modulus at the respective prestrain levels. |
