Rao–Nakra sandwich beam with second sound

open access: yesPartial Differential Equations in Applied Mathematics, 2021
In this manuscript, we prove the well-posedness and exponential stability for a thermoelastic structure given by a Rao–Nakra sandwich beam. The system consists of two wave equations for the longitudinal displacements of the top and bottom layers, and one

On unique determination of an unknown spatial load in damped Euler-Bernoulli beam equation from final time output

open access: yes, 2022
In this paper, we discuss the role of the damping term mu u(t) in unique determination of unknown spatial load F(x) in a damped Euler-Bernoulli beam equation u (tt) + mu u(t) + (r(x)u(xx))(xx) = F(x)G(t) from the measured final time displacement u(T)(x) :

Periodic Solutions of the Euler-Bernoulli Equation for Vibrations of a Beam with Fixed Ends

open access: yesСовременные информационные технологии и IT-образование, 2020
The problem of time-periodic solutions of the quasilinear equation of forced vibrations of an I-beam with fixed ends is investigated. The nonlinear term and the right-hand side of the equation are time-periodic functions.

Application of ADM Using Laplace Transform to Approximate Solutions of Nonlinear Deformation for Cantilever Beam

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2016
We investigate semianalytical solutions of Euler-Bernoulli beam equation by using Laplace transform and Adomian decomposition method (LADM). The deformation of a uniform flexible cantilever beam is formulated to initial value problems.
