Effect of Stress on the Dynamic Modulus of Concrete

what might be called the "purely elastic" modulus of elasticity of a specimen. The dis­ advantage of this method, however, is that the resonant frequency is determined at a zero stress and, therefore, the dynamic modulus of elasticity is the "purely elastic" property at a zero stress intensity. To overcome this disadvantage, the vibratory

Static Modulus - an overview | ScienceDirect Topics

The dynamic modulus of elasticity test apparatus is limited to laboratory testing where it is extremely useful for assessing durability of concrete, such as deterioration from chemical attack. It is also possible to determine the dynamic modulus of elasticity of concrete using the ultrasonic pulse velocity apparatus [1,33].

Dynamic Young's modulus is determined using the resonant frequency in either the flexural or longitudinal mode of vibration. The dynamic shear modulus, or modulus of rigidity, is found using torsional resonant vibrations. Dynamic Young's modulus and dynamic shear modulus are used to compute Poisson's ratio.
