Dynamic Young’s modulus is determined using the resonant frequency in the flexural mode of vibration. Dynamic Young’s modulus and dynamic shear modulus are used to compute Poisson’s ratio.

Link to Active This link will always route to the current Active version of the standard. The rod and bar geometries are described in the main body. Flat plates and disks may also be measured similarly, but the required equations for determining the moduli are not addressed herein.
Dynamic Young’s modulus is determined using the resonant frequency in x1259 flexural mode of vibration.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. No items in cart. The dynamic elastic properties of a material can therefore be computed asm the geometry, mass, and mechanical resonant frequencies of a suitable rectangular or cylindrical geometry test specimen of that material can be measured.

The transient signals are analyzed, and the fundamental resonant frequency is isolated and measured by the signal analyzer, which provides a numerical reading that is or is proportional to either the frequency or the period of the specimen vibration. The rod and bar geometries are described in the main body.
This standard is also available to be included in Standards Subscriptions. This ensures that you are always up-to-date and saves you both time and money. The dynamic shear modulus, or modulus of rigidity, is found using torsional resonant vibrations.

The specimens are subjected to minute strains; hence, the moduli are measured at or near the origin of the stress-strain curve, with the minimum possibility of fracture. There is no requirement for complex support systems that require elaborate setup or alignment.
