TL;DR: In this paper, a non-linear theory of composite thin-walled beams accounting for finite displacements and arbitrarily large twist angles is presented, valid for beams of arbitrary open and closed cross-sections and accounts for various non-classical effects like anistropy, transverse shear deformation and constrained warping.

TL;DR: In this paper, the authors considered two structural systems: rotating turbomachinery blades and thin-walled beam structures spinning about their longitudinal axis, and the implications on their vibration and instability of conservative and gyroscopic forces considered in conjunction with a temperature field that yields the degradation of elastic properties are investigated.
Abstract: In this study, problems related to the thermoelastic modeling and behavior of thin-walled beams made of functionally graded materials (FGMs) are addressed. In this context, two structural systems are considered: (i) rotating turbomachinery blades, and (ii) thin-walled beam structures spinning about their longitudinal axis. In all these cases, the structures operate in a high temperature environment. Under the spinning speed, gyroscopic forces are generated. Although conservative in nature, under their influence, as in nonconservative systems, instabilities by flutter and divergence can occur. In this context, the implications on their vibration and instability of conservative and gyroscopic forces considered in conjunction with a temperature field that yields the degradation of elastic properties are investigated. A continuously graded variation in composition of the ceramic and metal phases across the beam wall thickness in terms of a simple power law distribution is implemented. Results highlig...

TL;DR: In this article, a theoretical model is developed for the dynamic analysis of composite thin-walled beams with open or closed cross-sections, incorporating the shear flexibility (bending and warping shear) as well as a state of initial stresses.

TL;DR: In this article, the authors validate a class of refined thin-walled beam model that has been extensively used towards the study, among others, of dynamic response, static aeroelasticity and structural/aero-elastic feedback control.

TL;DR: In this paper, a theoretical model is developed for the stability analysis of composite thin-walled beams with open or closed cross-sections, which incorporates the shear flexibility (bending and non-uniform warping), featured in a consistent way by means of a linearized formulation based on the Reissner's Variational Principle.
