Generalized Euler – Bernoulli Beam Theory with Return Potential

Reinforced concrete structures
In 1749, L. Euler, building on the ideas of Jakob and Daniel Bernoulli, formulated beam theory in an exact formulation with the hypothesis of plane sections. Later, P.-S. Girard linearized the curvature, simplifying the derivation of analytical solutions, and B.P.E. Clapeyron expressed it in terms of derivatives of the deflection function. As a result,

Natural frequency of beams with embedded piezoelectric sensors and actuators

, 2007
A mathematical model is developed to study the natural frequency of beams with embedded piezoelectric sensors and actuators. The piezoelectric sensors/actuators in a non-piezoelectric matrix (host beam) are analyzed as two inhomogeneity problems by using

Vibrational Energy Flow Analysis of Corrected Flexural Waves in Timoshenko Beam – Part I: Theory of an Energetic Model

Shock and Vibration, 2006
In this paper, an energy flow model is developed to analyze transverse vibration including the effects of rotatory inertia as well as shear distortion, which are very important in the Timoshenko beam transversely vibrating in the medium-to-high frequency

Novel weak form quadrature elements for second strain gradient Euler-Bernoulli beam theory

, 2018
Two novel version of weak form quadrature elements are proposed based on Lagrange and Hermite interpolations, respectively, for a sec- ond strain gradient Euler-Bernoulli beam theory. The second strain gradient theory is governed by eighth order partial differential equa- tion with displacement, slope, curvature and triple derivative of dis- placement ...
