Geometrically nonlinear theory of initially imperfect sandwich curved panels incorporating noclassical effects

摘要

A comprehensive geometrically nonlinear theory of initially imperfect doubly curved sandwich shells is devel- oped. The theory encompasses sandwich structures with dissimilar face sheets constructed of laminate composites and with the core modeled as an orthotropic body featuring strong or soft behaviors. The theory includes the dynamic as well as the temperature and moisture effects. As a special case, a range of related applications of the theory of sandwich shells with soft core are presented.
