MECHANISM OF BIAXIAL THERMAL RATCHETING DEFORMATION IN THIN-WALLED CYLINDRICAL SHELLS

摘要

摘要: 本文通过循环受载轴对称弹塑性有限元计算,详细阐述了内压及轴向压应力作用下薄壁筒壳(双轴问题)R₁型、R₂型热棘轮变形机理。

Abstract: In this paper, thermal Ratcheting mechanism R₁ and R₂ (stress/strain variational process and its regularity) in the thin-walled cylindrical shells subjected to biaxial stress and cyclic temperature distribution has been investigated by using elastic-plastic finite element analysis under cyclic loading.
