Finally, the correlation between the

elastic constant (k) of a damping system under the influence of a harmonic force with the material parameters needs further study.

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

elastic constant [c.

2006) and Harrison and Hindman (2007)) demonstrated that there is no consistent pattern of equivalency between the

elastic constants and

elastic constant ratios measured using different test methods.

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.

Despite the great variety of literature available on the identification of the

elastic constants of laminated plates, there are very few studies dedicated to the problems of the estimation of the elastic parameters of stiffened plates.

Bodig and Jayne (1982) reported a series of

elastic constant ratios with a generalized [E.

Previous research has noted differences between solid-sawn lumber (SSL) and SCL materials in terms of the

elastic constant ratios (Hindman et al.

2005b) have noted differences in the

elastic constant ratios and torsional rigidity terms between solid-sawn lumber and SCL materials.

The transverse MOE and all shear moduli values were calculated using

elastic constant ratios for SCL given by Hindman (1999), based on the measured value of [E.

For the mechanical system formed of mass m5 and the segment of the shaft with the

elastic constant of [c.
