The Static and the Dynamic Modulus of Elasticity of Recycled Aggregate Concrete

Advanced Materials Research, 2014
The 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, 1964
A 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, 2011
Young’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, 1961
A 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.

Influence of Water Content on Dynamic Elastic Modulus of Concrete

Applied Mechanics and Materials, 2013
Water content is one of key effect factors on the dynamic elastic modulus, which is an important damage assessment index of concrete structures induced by freeze-thaw cycles, fire and chemical attacks. Through the ultrasonic and bending vibration test, the regularity of dynamic elastic modulus changed with the water content of concrete specimens was ...

Measurement of the dynamic elastic modulus of short staple fibers

Journal of Applied Polymer Science, 1974
A description is given of the equipment and measurement techniques which have been developed for the determination of the dynamic elastic modulus of staple fibers of length 25 mm or less. The dynamic elastic modulus, often called the sonic modulus, is determined by means of the pulse propagation method with the aid of a specially designed constant ...

Dynamic method of measuring torsional modulus of elasticity

Journal of Scientific Instruments, 1962
A 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%.
