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)R_1型、R_2型热棘轮变形机理。
This paper elaborates the deformation mechanism of thin-walled shell (biaxial problems) R-1 and R-2 thermal ratcheting under the action of internal pressure and axial compressive stress through the cyclic loading axisymmetric elastoplastic finite element method.
