Measurement of the dynamic modulus of elasticity of wood panels
Frontiers of Forestry in China, 2006This study investigated the dynamic modulus of elasticity (DMOE) of wood panels of Fraxinus mandshurica, Pinus koraiensis, and Juglans mandshurica using the natural frequency measurement system of fast Fourier transform (FFT). The results were compared with the static modulus of elasticity (E S) tested by a mechanical test machine.

In that the elastic constants, Cij, which may be used to calculate the bulk, shear, and Young’s moduli, as well as the Debye temperatures of polycrystalline materials, are related to the electronic properties and in some cases have first been calculated from principles, they form a bridge between the mechanical properties of materials and their ...

Graphical Analysis of Static and Dynamic Elastic Modulus of Shaving Sheet
Journal of Multimedia, 2013The traditional measurement method of thin wood-based panel’s elastic modulus is carried out on the test piece for three-point or four-point bending static deformation test, the determination process is complex, time consuming, and makes damage to specimen.

Journal of Fluid Mechanics, 2001
The interaction of a laser-induced cavitation bubble with an elastic boundary is investigated experimentally by high-speed photography and acoustic measurements. The elastic material consists of a polyacrylamide (PAA) gel whose elastic properties can be controlled by modifying the water content of the sample.

The Static and the Dynamic Modulus of Elasticity of Recycled Aggregate Concrete
Advanced Materials Research, 2014The main aim of this contribution is description of the static and the dynamic modulus of elasticity of concrete containing recycled aggregate. Recycled construction and demolition waste, especially recycled concrete, is able to use as an aggregate for concrete, but using of recycled aggregate has a negative impact of concrete characteristic.

Dynamic method of measuring Young's modulus of elasticity
Journal of Scientific Instruments, 1964A dynamic method of measuring the Young's modulus of elasticity of a solid has been developed. This uses the resonance in the flexural vibrations of loaded fixed-free bars at frequencies below 200 c/s. The frequency equation has been derived for a fixed-free prismatic bar, carrying a heavy mass of precise finite dimensions at the free end.

Comparison of the static and dynamic elastic modulus in carbonate rocks
Bulletin of Engineering Geology and the Environment, 2011Young’s modulus is one of the most important mechanical parameters in building materials used to assess both the appropriateness of a material as well as its mechanical stability. The paper reports a study to predict the elastic modulus for ten carbonate rocks using the ultrasonic technique.

Measurement of the Modulus of Dynamic Elasticity of Staple Fibers
Textile Research Journal, 1961A description is given of an apparatus with the aid of which the modulus of dynamic elasticity of fibers can be determined at about 1000 cycles/sec. as a function of the strain. In principle the dynamic elasticity constant of the fiber is determined by measuring the resonance frequency of a cantilever spring which is loaded with the fiber.

Dynamic method of measuring torsional modulus of elasticity
Journal of Scientific Instruments, 1962A dynamic method of measuring torsional modulus of elasticity, at frequencies below 250 c/s, has been developed and has been used to measure this property for commercially pure specimens of copper, silver and constantan. The results were found to be reproducible to better than 0.8%.
