We were able to show that the conical shape minimizes, in a first approximation, the free energy of the system when the ratio between the bend rigidity and

elastic constant are in the appropriate range and that the transition between the flat and buckled state is second-order like.

The analysis of the diffused light being realized by an interferometer of Fabry-Perot, this technique makes it possible to measure the propagation velocity of the sound and then enables us to determine

elastic constants of studied material.

4] and the part of the crankshaft (which is reduced and has the

elastic constant [c.

One area of structural design affected by the

elastic constant ratios and torsional rigidity differences is the design of beams for lateral torsional buckling as expressed in the National Design Specification (NDS) for wood construction (AF & PA 2001) and load resistance factor design (LRFD) provisions (AF & PA 1996).

This mesh is already very fine, especially in the area of interest, and further refinement would not be appropriate since the results are mainly influenced by the set of

elastic constants.

0] are the Lame

elastic constants of the spacetime continuum, substituting for [[u.

Previous researchers have found differences in the

elastic constants and

elastic constant ratios of structural size solid-sawn lumber and structural composite lumber (SCL) materials using a variety of bending and torsion test methods.

Elastic constants of continuous fiber reinforced composites with various types of constituents were determined by Hashin & Rosen [1], Hashin [2], Whitney [3] and Chen and Chang [4].

In this paper, only the stress ratio, volumetric strain and hypothetical

elastic constant, [E.

In this paper, we focus on the

elastic constant measurement of metal alloy materials especially in a temperature changing environment.

0] is the harmonic force, [omega] is frequency that can be described as [omega] = 2[pi]/T (T is the period of oscillation), k is the

elastic constant, m is the mass, and [[omega].

0], mandQ are the

elastic constant of the cantilever, the oscillation frequency of the driver, the resonant frequency, the mass and quality factor of the cantilever, respectively.
