Elastic Instability and Curved Streamlines
Physical Review Letters, 1996Hydrodynamic instabilities occur in the motion of non-Newtonian polymeric liquids at low flow rates that are entirely absent in the corresponding motions of Newtonian fluids. We develop a dimensionless criterion that characterizes the critical conditions for onset of elastic instabilities in two-dimensional, single-phase isothermal viscoelastic flows ...

The elastic stability of curved beams
International Journal of Mechanical Sciences, 1967Abstract 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 ...

Annals of Global Analysis and Geometry, 1998
The shape of a bent thin rod (a plane elastic curve) is given explicitly as soon as one knows certain three parameters. The basis of that is a theorem due to the author [cf. \textit{A. Linnér}, Nonlinear Anal., Theory Methods Appl. 21, 575-593 (1993; Zbl 0809.53006), J.

Elastic equilibrium of curved thin films
Physical Review E, 1994We present a unified theory of the bending of crystalline films that accounts for both elastic effects and crystal defects. Our theory predicts a transition from a bent coherent film with no dislocations to an incoherent, dislocated one as the film thickness or curvature is increased.

The Elasticity of Substitution and the Shape of the Transformation Curve
Economica, 1973The purpose of this paper is to determine, for a country producing two goods with two factors, how the shape of the transformation curve depends on the elasticities of substitution in production in the two industries. Harry Johnson' has examined the shape of the transformation curve and has concluded that it is much less bowed out than is traditionally

ON SPHERICAL ELASTIC CURVES: SPHERICAL INDICATRIX ELASTIC CURVES
2016In this paper, we study spherical elastic curves corresponding spherical indicatrix of regular curves with non-vanishing curvature in Euclidean 3-space. From classical variational problem of elastic curves, we derive two Euler-Lagrange equations associated to actions of bending energy functional defined on tangent spherical indicatrix of curves in ...

On the stability of elastic curved bars
Acta Mechanica Sinica, 1987A general discussion about the stability of arbitrary elastic curved bars in space under combined actions of bending and twisting is given in this paper. A system of Eqs. (28)–(36) for perturbation functions near some equilibrium state is presented. With appropriate boundary conditions, the nontrivial solution corresponds to the critical state.

Journal of Engineering Materials and Technology, 1978
The principal purpose of this investigation was to study specimen size effects on elastic-plastic type R-curve using HY130 steel plate. Compact specimens ranging in size from 12T to 1T in planar dimensions and standardized on 1-inch thickness were used.
