Distribution Character of Structural Stress for Aluminum Alloy Thick Plate

Abstract:

Article Preview

Generation of structural stress in aluminum alloy thick plate is divided into three stages including the early, stable and late period using thermodynamics and elasticity theory. With FEM and mechanical state of materials, nonuniform plastic deformation is discussed, and distributions and characters of structural stress are analysized in each stage. Finally, experimental results agreed with date of the FEM. This truth demonstrated that mechanism of stress that changes in the process of thermal field works on formation of the final residual stress in the thick plate.
