In this paper some fundamental considerations on application of the boundary element method to thin elastic shell problems are given generally by taking a displacement approach which is adaptable to any type of boundary conditions. The system of integral equations for shells with arbitrary middle ...

This paper describes an efficient monolithic method for shell-fluid interaction problems based on the fluid pressure Poisson equation (PPE). The PPE is derived so as to be consistent with the coupled equation system for the shell-fluid interaction. In the proposed method, the fluid pressure is ...
The constitutive equations for the materials of the shell and the viscoelastic core are given by: (6)σL=CLεL,L=1,2 where the superscripts 1 and 2 identify the shell and the viscoelastic core, respectively. View chapterExplore book Design formulae for simple structures In Metal Foams, 20...
摘要: We prove that the wavevectors of the off-shell Bethe ansatz equation for the inhomogeneous SU(2) lattice vertex model render in the quasiclassical limit the solutions of the Knizhnik-Zamolodchikov equation.关键词: QUANTUM DYNAMICS PERIODIC COSINE POTENTIAL OHMIC DISSIPATION NONLINEAR RESPONSE...
