Residual Stress Analysis Due to Chemomechanical Coupled Effect, Intrinsic Strain and Creep Deformation During Oxidation

摘要: Metal oxidation at high temperature is often accompanied with the stress generation both in metal substrate and growing oxide scale. In this paper, taking into account growth strain, intrinsic strain creep deformation, a new analysis model to characterize residual evolutions during an isothermal process developed on basis of mechanical-balance moment-equilibrium equations. model, are coupled based evolving equation, which reduces Clarke’s assumption if influence scale ignored. The curvature describing bending system expressed. Euler numerical method adopted simulate evolution comparisons among present Zhang’s solution experimental results also performed. Finally, effects constants, thickness distribution scale/metal discussed.
