今天写有关板壳理论的第一节,有关各向同性薄板的小挠度弯曲的模型建立。也就是基于 Kirchhoff 计算假定的应用弹性力学的薄板问题的建模。 特别地,这次会从真实结果出发,反推应用弹性力学的简化建模是否合理。 一、从真实结果出发,深入解读 Kirchhoff 计算假定: 真实结果表明: σx,σy,τxy,τxz,τyz,σz 这六...
The Kirchhoff-Love theory also known as the classical plate theory (CPT) is based on three basic assumptions. First, the plate is assumed to be inextensible in the transverse direction ɛzz=0 so w=woxy. Then, it is assumed that the transverse shear deformations are negligible ɛxz=0,...

The Kirchhoff–Love shell theory is recasted in the frame of the tangential differential calculus (TDC) where differential operators on surfaces are formulated based on global, three-dimensional coordinates. As a consequence, there is no need for a parametrization of the shell geometry implying curvi...
Geometrically Exact Finite Element Formulations for Slender Beams: Kirchhoff-Love Theory Versus Simo-Reissner Theory The present work focuses on geometrically exact finite elements for highly slender beams. It aims at the proposal of novel formulations of Kirchhoff-Love type, a detailed review of existi...

Then, we deal with the truncated version of the Uflyand–Mindlin theory as proposed by the present writer. This theory was independently asymptotically justified by Mindlin, Goldenveiser, Kaplunov and Nolde, and Sayir, but did not yet fully resonate with the research community. We present the...
A new formulation of the thin-shell equilibrium equations, under the Kirchhoff-Love hypotheses, is presented so that a complete self-consistent theory of thin elastic shells is produced. This new shell theory is used elsewhere to analyse the buckling of thin cylindrical shells under axial ...
