Dynamics of Laminated Timoshenko Beams
Journal of Dynamics and Differential Equations, 2017The authors describe the long-time dynamics of a Timoshenko system consisting of two identical beams joined by a thin adhesive layer. After some transformations, the authors obtain the coupled system of three evolution equations \(\rho w_{tt}+G\varphi _{x}+g_{1}(w_{t})+f_{1}(w,\xi ,s)=h_{1}\), \(I_{\rho }\xi _{tt}-G\varphi -D\xi _{xx}+g_{2}(\xi _{t ...

Laminating Effects in Glued-Laminated Timber Beams
Journal of Structural Engineering, 1995Existing lamination and beam test results were analytically reviewed to quantify the laminating effect for European and North American glued-laminated (glulam) timber. The laminating effect is defined as the increase in strength of lumber laminations when bonded in a glulam beam compared with their strength when tested by standard test procedures ...

<div class="htmlview paragraph">In this work it is presented an adaptation for beams of Di Sciuva’s theory of laminated plates. This theory accepts that in each lamina plane sections remain plane and other assumptions accepted for isotropic beams.</div> <div class="htmlview paragraph">A computer program was made to solve the equations

Hybrid laminated Timoshenko beam
Journal of Mathematical Physics, 2017We consider the hybrid laminated Timoshenko beam model. This structure is given by two identical layers uniform on top of each other, taking into account that an adhesive of small thickness is bonding the two surfaces and produces an interfacial slip.

13th Structures, Structural Dynamics, and Materials Conference, 1972
This paper is a continuation of Ref. 1 and its extension to dynamic problems. As in Ref. 1 the underlying assumptions about the kinematics of the beam deformation are: a) deformations are elastic and small such that the linear elasticity theory is applicable; b) perfect bond is realized between adjacent laminae; c) Bernoulli's hypothesis of planar ...

A glued laminated timber beam or slab (10) comprises one beam body (11) and one or two adjacent strips or sheets (12), separated by an adhesive interface (13) each, wherein the height of the adjacent strip (s) or sheet (s) (12) is between 15 and 25% of the height of the beam or slab (10).

Nonuniform laminated beam of Lord–Shulman type
Studies in Applied Mathematics, 2022AbstractThe nonuniform thermoelastic laminated beam of the Lord–Shulman type is considered. The model is a two‐layered beam with structural damping due to the interfacial slip. The well‐posedness is proved by the semigroup theory of linear operators approach together with the Lumer–Phillips theorem.

Journal of Sound and Vibration, 1974
Governing equations in the form of simultaneous ordinary differential equations have been derived for natural vibration analysis of isotropic laminated beams. This formulation includes significant secondary effects such as transverse shear and rotatory inetia. Through a numerical example, the influence of these secondary effects has been studied.
