Dynamic Characteristics of Curved Pair Members subjected to Axial Compress

Letters to the Editor Discussion of “dynamic Stability of Cables Subjected to an Axial Periodic Load”

In the referenced paper [ 11, the author examines the stability of the planar, linear response of a suspended cable subjected to harmonic axial loading. The study is motivated by a desire to understand the dynamic stability of cables employed in structures such as cablestayed bridges or guy-towers. In these applications, the harmonic axial load derives from the dynamic reaction of the structure...

Stochastic bifurcation characteristics of SMA intravascular stent subjected to radial and axial excitations.

A kind of shape memory alloy (SMA) hysteretic nonlinear model is developed, and the stochastic bifurcation characteristics of SMA intravascular stents subjected to radial and axial excitations are studied in this paper. A new nonlinear differential item is introduced to interpret the hysteretic phenomena of SMA strain-stress curves, and the dynamic model of SMA intravascular stent subjected to ...

An Elasticity Solution for Static Analysis of Functionally Graded Curved Beam Subjected to a Shear Force

In this paper, using 2-D theory of elasticity, a closed-form solution is presented for stressdistributions and displacements of a FG curved beam under shear force at its free end. The materialproperties are assumed to vary continuously through the radial direction based on a simple power lawmodel and Poisson’s ratio is supposed to be constant. In order to verify the solution, it is shown that a...

Dynamic response of tubular joints with an annular void subjected to a harmonic axial load

Dynamic responses of adhesively bonded tubular joints subjected to a harmonic axial load were evaluated with the use of a shear lag model. Adherents were assumed to be elastic and the adhesive was taken to be a viscoelastic material. Effects of tubular joint geometries, material properties and adhesive properties on the dynamic response of the system were investigated. The results showed that t...
