A Pseudospectral Approach for Kirchhoff Plate Bending Problems with Uncertainties
This paper proposes a pseudospectral approach for the Kirchhoff plate bending problem with uncertainties. The Karhunen-Loève expansion is used to transform the original problem to a stochastic fourth-order PDE depending only on a finite number of random variables. For the latter problem, its exact solution is approximated by a gPC expansion, with the coefficients obtained by the sparse grid met...
متن کاملLocal Projection-Based Stabilized Mixed Finite Element Methods for Kirchhoff Plate Bending Problems
and Applied Analysis 3 Let {T h } h>0 be a regular family of triangulations ofΩ (cf. [1, 20]); h := max K∈Th h K and h K := diam(K). Let E h be the union of all edges of the triangulation T h and E h the union of all interior edges of the triangulationT h . For any e ∈ E h , denote by h e its length. Based on the triangulationT h , let the finite element spaces be given by Σ h := {τ ∈ Σ : τ| K ...
متن کاملLipschitz stability in inverse problems for a Kirchhoff plate equation
In this paper, we prove a Carleman estimate for a Kirchhoff plate equation and apply the Carleman estimate to inverse problems of determining spatially varying two Lamé coefficients and the mass density by a finite number of boundary observations. Our main results are Lipschitz stability estimates for the inverse problems under suitable conditions of initial values and boundary val-
متن کاملGeometrically Nonlinear Analysis of Plate Bending Problems
In the previous six chapters, we have discussed the application of T-elements to various linear problems. This approach can also be used to solve both geometrically [8-10,12] and materially [1,18] nonlinear problems. The former are treated in this chapter and the latter are addressed in Chapter 8. The first application of T-elements to nonlinear plate bending problems was by Qin [8], who presen...
متن کاملFinite Elements for Reissner-Mindlin plate bending problems
We consider the plate bending problem in the framework of the Reissner-Mindlin theory. For a clamped plate, the problem can be written in variational form as follows. Find (θ, w) ∈ (H 0 (Ω)) ×H 0 (Ω) : ∫ Ω Cε(θ) : ε(η) + μ t−2 ∫ Ω (∇w − θ) · (∇v − η) = ∫
