The elastic stability of curved beams

International Journal of Mechanical Sciences, 1967
Abstract Calculations are made of the ranges of validity of three theories used for investigating the instability of curved beams. These include linear and nonlinear (elastica) extensible theories, as well as a nonlinear inextensible one. The specific example chosen for the investigation is that of a curved beam hinged to fixed supports at its ends ...

Elastic Stability of Curved Members

Journal of Structural Engineering, 1983
A general solution method of a system of coupled differential equations governing the elastic buckling of thin-walled curved members is presented. The finite element displacement method is formulated based on a variational principle. The stiffness and stability properties of the finite elements are consistent and are obtained within the bounds of ...

The Second-Order L2-Flow of Inextensible Elastic Curves with Hinged Ends in the Plane

, 2014
In this article, we study the evolution of open inextensible planar curves with hinged ends. We obtain long time existence of C∞-smooth solutions during the evolution, given the initial curves that are only C2-smooth with vanishing curvature at the ...

Unfolding a Curved Elastic Sheet

Journal of Mechanical Engineering Science, 1981
A curved elastic sheet is flattened on a rigid flat plate by vertical end forces. The problem is governed by a non-dimensional parameter, B, which signifies the relative importance of flexural rigidity to the applied force and the natural radius.

Horizontally Curved Plates on Elastic Foundations

Journal of Structural Engineering, 1987
An analytical solution is presented for the analysis of horizontally curved (or sector) plates on elastic foundations. Circular concrete pavements of highways may be analyzed by this method. Plates with different boundary conditions and subjected to various types of loadings can be treated by the proposed method.

Elastic Properties of Curved Tubes

Journal of Fluids Engineering, 1943
Abstract A theory of flexibility of pipe bends perpendicular to the plane of the bend has been established. Experimental results are given in this paper verifying the derived bending equations. Results show the pipes to be more flexible than expected from the application of the “rod” theory.

Crack curving in anisotropic elastic solids

Engineering Fracture Mechanics, 1993
Abstract The stress analysis for slightly curved cracks in an elastic anisotropic homogeneous solid is given by using a perturbation method combined with the approach of Muskhelishvili. For predicting the direction of the crack growth, higher order asymptotic stress fields at the tips of quasi-statically growing cracks under planar loading conditions
