Specimens of these materials possess specific mechanical resonant frequencies that are determined by the elastic modulus, mass, and geometry of the asym specimen. There is no requirement for complex support systems that require elaborate setup or alignment. Please first log in with a verified email before subscribing to alerts. Standards Subsctiption may be the perfect solution.
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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Deviations in specimen dimensions or mass and internal flaws cracks, delaminations, inhomogeneities, porosity, etc will change the resonant frequency for that specimen.

As the voice of the U. Specimen supports, impulse locations, and signal pick-up points are selected to induce and measure specific modes of the transient vibrations. Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

Dynamic Young’s modulus is determined using the resonant frequency in the flexural mode of vibration. You need to log in before adding standards to the monitoring service. Remember me for one month. The actual modulus of each specimen need not be determined as long as the limits of the selected frequency range are known to include the resonant frequency that the specimen must possess if its geometry and mass and internal structure are within specified tolerances.
The following editions for this book are also available The appropriate fundamental resonant frequencies, dimensions, and mass of the specimen are used to calculate dynamic Young’s modulus, dynamic shear modulus, and Poisson’s ratio. Are you sure you want to empty the cart?
