APPLICATION OF TIMOSHENKO BEAM THEORY FOR DEFINITION OF LOADS ON THE PIPELINE

Oil and Gas Studies, 2017
For definition of stresses and loads through measured displacements of pipeline axis it is necessary to calculate derivatives of approximate function. The error of defined stresses is in direct dependence on order of derivatives, necessary for their definition. Application of Timoshenko beam theory allows to reduce the order of derivatives.

internal constraints reactive stresses and the timoshenko beam theory

Journal of Elasticity, 2001
It is shown that the kinematical assumptions of the Timoshenko theory for shearable beams can be regarded as internal constraints, some involving the first, others the second deformation gradient; such constrains are thought of as maintained by reaction stresses and hyperstresses of the type occurring in non-simple materials of grade 2. It is discussed

Application of Timoshenko beam theory to the estimation of structural response

Engineering Structures, 2016
Abstract Multi-story buildings are usually instrumented at a limited number of floors. Consequently, the structural response (e.g., acceleration, displacement) at the non-instrumented floors remains unknown and needs to be estimated using the acceleration data recorded at the instrumented floors.

The thermal effect on vibration of single-walled carbon nanotubes using nonlocal Timoshenko beam theory

, 2008
This paper is concerned with the use of the nonlocal Timoshenko beam model for free vibration analysis of single-walled carbon nanotubes (CNTs) including the thermal effect. Unlike the Euler beam model, the Timoshenko beam model allows for the effects of

Asymptotic Derivation of Shear Beam Theory from Timoshenko Theory

Journal of Engineering Mechanics, 2007
A systematic reduction of Timoshenko beam theory to shear beam theory is presented and compared to a parallel reduction to Euler–Bernoulli theory. The agreement between Timoshenko and shear theories is seen to improve as the ratio of Young’s modulus to shear modulus increases, as the mode number increases, and as the beam becomes fatter, which are the ...

Flexural Vibrations in Uniform Beams According to the Timoshenko Theory

Journal of Applied Mechanics, 1953
Abstract The general series solution is given for the flexural vibrations in a uniform beam according to the Timoshenko equations, which include the secondary effects of shear and rotatory inertia. In addition, the series solution is presented for the case of a pin-ended beam. For the special case of a concentrated transient force at the
