SIMILARITY SOLUTIONS AND CONSERVATION LAWS FOR THE BEAM EQUATIONS: A COMPLETE STUDY

open access: yesActa Polytechnica, 2020
We study the similarity solutions and we determine the conservation laws of various forms of beam equations, such as Euler-Bernoulli, Rayleigh and Timoshenko-Prescott.

Distributional solution concepts for the Euler–Bernoulli beam equation with discontinuous coefficients [PDF]

open access: yesApplicable Analysis, 2007
We study existence and uniqueness of distributional solutions w to the ordinary differential equation with discontinuous coefficients and right-hand side. For example, if a and w are non-smooth the product a · w″ has no obvious meaning. When interpreted on the most general level of the hierarchy of distributional products discussed by Oberguggenberger,

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

A Numerical Method of the Euler-Bernoulli Beam with Optimal Local Kelvin-Voigt Damping

open access: yesJournal of Applied Mathematics, 2014
This paper deals with the numerical approximation problem of the optimal control problem governed by the Euler-Bernoulli beam equation with local Kelvin-Voigt damping, which is a nonlinear coefficient control problem with control constraints. The goal of

On the Forced Vibration of Bending-Torsional-Warping Coupled Thin-Walled Beams Carrying Arbitrary Number of 3-DoF Spring-Damper-Mass Subsystems

open access: yesMathematics, 2022
This paper presents an analytical transfer matrix modeling framework for the forced vibration of a bending-torsional-warping coupling Euler-Bernoulli thin-walled beam carrying an arbitrary number of three degree-of-freedom (DOF) spring-damper-mass (SDM ...

Static and free vibration of axially loaded functionally graded beams based on the first-order shear deformation theory [PDF]

open access: yes, 2013
The first-order shear deformation beam theory for static and free vibration of axially loaded rectangular functionally graded beams is developed. In this theory, the improved transverse shear stiffness is derived from the in-plane stress and equilibrium ...

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) :

On generalized nonlinear Euler-Bernoulli Beam type equations

open access: yesActa Universitatis Sapientiae, Mathematica, 2018
Abstract This paper is devoted to the study of a nonlinear Euler-Bernoulli Beam type equation involving both left and right Caputo fractional derivatives. Differently from the approaches of the other papers where they established the existence of solution for the linear Euler-Bernoulli Beam type equation numerically, we use the lower and

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.
