Investigation of constitutive model of as-extruded spray-forming 7055 aluminum alloy based on BP artificial neural network

Investigation of constitutive model of as-extruded spray-forming 7055 aluminum alloy based on BP artificial neural network

Gleeble physical simulation technique was employed to investigate the high-temperature flow stress characteristics of the studied spray forming 7055 aluminum alloy. Simultaneously, the Arrhenius constitutive model which couples the parameter of true strain and the BP artificial neural network consti...
