Determination of Young's modulus for spruce, fir and isotropic materials by the resonance flexure method with comparisons to static flexure and other dynamic methods

Wood Science and Technology, 1996
Dynamic methods provide rapid and accurate means to determine Young's modulus, i.e. the modulus of elasticity, of wood. For dry, clear specimens of epicea commun (Norway spruce, picea excelsa) and sapin pictine (silver fir, abies amabilis) we present a comparison of results from tests by a resonance flexure method with results obtained from four-point ...

Flexure of Statically Indeterminate Cracked Beams

Journal of Engineering Mechanics, 1985
The influence of nonpropagating cracks on redistribution of internal forces in the flexure of statically indeterminate beams is studied by modeling crack as a rotational spring of known compliance, where the compliance is determined by using the relationship between the stress intensity factor for Mode I cracks and the compliance itself. The problem is

Static flexural behavior of bamboo as a functionally graded material and the effect of heat on dynamic flexural modulus

Journal of Building Engineering, 2021
Abstract The objective of the present investigation is to study the static and dynamic flexural behavior of bamboo as a functionally graded material to determine the Static Flexural Modulus (SFM) for untreated bamboo samples and to evaluate the effect of heat on the variation of the Dynamic Flexural Modulus (DFM).

On the flexural vibration frequencies of statically loaded beams

Meccanica, 1972
The problem of vibrations of structures with heavy static loads is a non linear one, and, as such, of difficult solution in its general formulation.

Dynamic and Static Flexural Appraisal of Resin-based Composites: Comparison of the ISO and Mini-flexural Tests

Operative Dentistry, 2018
SUMMARY The objective of this study was to determine the influence of specimen dimension and conditioning medium on the dynamic and static flexural properties of resin-based composites (RBCs). One conventional (Filtek Z350) and two bulk-fill RBCs (Filtek Bulk-fill and Beautifil-Bulk Restorative) were evaluated.

Static–Dynamic Relationship for Flexural Free Vibration of Extensible Beams

International Journal of Structural Stability and Dynamics, 2018
This technical note presents a static–dynamic relationship for the flexural free vibration analysis of beams in tension with some specific boundary conditions. It is shown to be possible that a free vibration system can be solved via a static analysis approach to determine the natural frequencies of the beam with tension forces.
