Exact and Numerically Stable Expressions for Euler-Bernoulli and Timoshenko Beam Modes [PDF]
, 2018 In this work we present a general procedure for deriving exact, analytical, and numerically stable expressions for the characteristic equations and the eigenmodes of the Timoshenko and the Euler-Bernoulli beam models. This work generalizes the approach recently described in Goncalves et al. (P.J.P. Goncalves, A. Peplow, M.J.

A modeling method for vibration analysis of cracked beam with arbitrary boundary condition
Journal of Ocean Engineering and Science, 2018 This paper establishes a cracked Timoshenko beams model to investigate the vibration behavior based on the ultraspherical polynomials. Timoshenko beam theory is applied to model the free vibration analysis of the cracked beam and the numerical results ...

On the stability of Timoshenko systems with Gurtin-Pipkin thermal law [PDF]
arXiv, 2013 We analyze a differential system describing a Timoshenko beam coupled with a temperature evolution of Gurtin-Pipkin type. A necessary and sufficient condition for exponential stability is established in terms of the structural parameters of the equations.

A Micropolar Peridynamic Theory in Linear Elasticity [PDF]
, 2014 A state-based micropolar peridynamic theory for linear elastic solids is proposed. The main motivation is to introduce additional micro-rotational degrees of freedom to each material point and thus naturally bring in the physically relevant material length scale parameters into peridynamics. Non-ordinary type modeling via constitutive correspondence is

Transverse Vibration of Axially Moving Functionally Graded Materials Based on Timoshenko Beam Theory
, 2015 The transverse free vibration of an axially moving beam made of functionally graded materials (FGM) is investigated using a Timoshenko beam theory. Natural frequencies, vibration modes, and critical speeds of such axially moving systems are determined ...
