Nonlinear Deformation Theory of Thin Shell

College of Astronautics and Material Engineering, National University of Defense Technology, Changsha 410073, P R China

摘要: 对薄壳的非线性变形,给出了应变与位移之间的精确关系.经过合理的简化,给出了壳的挠度与厚度同级的大变形基本公式.当薄壳为无限长柱形且作柱形变形时,精确地求得了壳的挠度与长度同级的大变形基本公式.

Abstract: The exact relation between strain and displacement is given for nonlinear deformation of thin shell.The fundamental formula of large deformation when the deflection is on the same class with the thickness of the shell is derived after simplified rationally.The fundamental formula of large deformation when the deflection is on the same class with the length of the shell is derived exactly for cylinder shell deformed cylindrical shaped.
