The first ANDES elements: 9-DOF plate bending triangles [PDF]

New elements are derived to validate and assess the assumed natural deviatoric strain (ANDES) formulation. This is a brand new variant of the assumed natural strain (ANS) formulation of finite elements, which has recently attracted attention as an ...

Static analysis of nanoplates based on the nonlocal Kirchhoff and Mindlin plate theories using DQM

Latin American Journal of Solids and Structures
In this study, static analysis of the two-dimensional rectangular nanoplates are investigated by the Differential Quadrature Method (DQM). Numerical solution procedures are proposed for deflection of an embedded nanoplate under distributed nanoparticles ...

Weakly Enforced Boundary Conditions for the NURBS-Based Finite Cell Method [PDF]

, 2012
In this paper, we present a variationally consistent formulation for the weak enforcement of essential boundary conditions as an extension to the finite cell method, a fictitious domain method of higher order. The absence of boundary fitted elements in

Optimal piezo-electro-mechanical coupling to control plate vibrations

, 2010
A new way of coupling electrical and mechanical waves, using piezoelectric effect, is presented here. Since the energy exchange between two systems supporting wave propagation is maximum when their evolution is governed by similar equations, hence, an ...

Polynomial stability of a Kirchhoff plate equation in the presence of a frictional damping, a fractional time delay, and a source term

Boundary Value Problems
We investigate the asymptotic behavior of a Kirchhoff plate equation with free boundary conditions in a bounded domain of R 2 $\mathbb{R}^{2}$ . The model involves frictional internal damping, a time delay condition of fractional type and a source term ...

MAGNETOELASTIC NATURAL VIBRATION OF CONDUCTIVE CIRCULAR PLATE IN CURRENT-CARRYING COILS

Jixie qiangdu, 2019
As for the conductive plate in magnetic field generated by current-carrying three parallel coaxial circular coils and spherical coils,based on the Kirchhoff plate theory,the magnetoelastic transverse vibration equation of the plate in magnetic field was ...

Bilinear spatial control of the velocity term in a Kirchhoff plate equation

Electronic Journal of Differential Equations, 2001
We consider a bilinear optimal control problem with the state equation being a Kirchhoff plate equation. The control is a function of the spatial variables and acts as a multiplier of the velocity term.

Natural Oscillations of Circular Sandwich Plates in the Temperature Field

Механика машин, механизмов и материалов
The effect of a homogeneous temperature field on the frequencies of natural oscillations of a circular sandwich plate is investigated. The hypothesis of a broken line is used as a kinematic one: for identical high-strength thin load-bearing layers, the ...

TOPOLOGY OPTIMIZATION PROBLEMS FOR CLAMPED KIRCHHOFF-LOVE PLATES

Annals of the Academy of Romanian Scientists Series on Mathematics and Its Application
Summary: Fixed domain approaches are used for some topology optimization problems of clamped Kirchhoff-Love plates: detection of a damaged zone using pointwise observation, respectively compliance minimization and the first eigenvalue maximization.
