Research on Creep Properties of AZ81 Alloy Based on BP Neural Network

Based on BP neural network method,the creep properties of AZ81 alloy was studied.The creep of the alloy was measured under the condition of 120-180℃ and 120-180 MPa,the collected experimental data were trained by using the structure of 3-12-1 BP neural network model.The resulst show that the error values are within 5% in addition to two errors,which can indicate that using BP neural network can improve the performance of AZ81 alloy.
