NONLINEAR STRAIN COMPONENTS OF GENERAL SHELLS WITH INITIAL GEOMETRIC IMPERFECTIONS

摘要

On the basis of nonlinear strain component formulations of three-dimensional continuum, this paper has derived the nonlinear strain component formulations of shells with initial geometric imperfections. The derivation is not confined to a special shell, therefore they possess general properties. These formulations provide the theoretical basis of the strain analysis for geometric nonlinear problems of shells with initial geometric
