This study investigates the compression deformation behavior of an Mg-Gd-Y-Nd-Zr alloy at temperatures ranging from 293 K to 573 and strain rates 293K 573K 1000 s−1 2100 using a split Hopkinson pressure bar. A modified Johnson-Cook (JC) constitutive model backpropagation neural network (BPNN) based on improved whale optimization algorithm (IWOA) are established. Four statistical metrics, including correlation coefficient (R), mean absolute error (MAE), percentage (MAPE), root square (RMSE), employed evaluate predictive accuracy two models. The findings indicate that flow stress is sensitive strain, rate, temperature. Increasing rate or decreasing temperature results in higher stress. Error calculations revealed has R 0.98731, MAPE 7.3653%, MAE 19.6305 MPa, RMSE 26.5704 MPa. In contrast, established IWOA-BPNN 0.99996, 0.58894%, 1.2671 1.7709 demonstrates accurately predicts alloy.
