The dynamic shear modulus, or modulus of rigidity, is found using torsional resonant vibrations. This is similar to the evaluation method described in Guide E Specimen supports, impulse locations, and signal pick-up points are selected to induce and measure specific modes of the transient vibrations. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

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.

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. You may delete a document from your Alert Profile at any time. Link to Active This link will always route to the current Active version of the standard. Any specimen with a resonant frequency falling outside the prescribed frequency range is rejected. Specimen descriptions should include any specific thermal treatments or environmental exposures that the specimens have received.

D Terminology for Plastics: Dynamic Young’s modulus and dynamic shear modulus are used to compute Poisson’s ratio. Specimens of these materials possess specific mechanical resonant frequencies that are determined by the elastic modulus, mass, and geometry of the test specimen.

Specimens of these materials possess specific mechanical resonant frequencies that are determined by the elastic modulus, mass, and geometry of the test specimen. Read more about subscriptions.

ASTM-C, –

A transducer for example, contact accelerometer or non-contacting microphone senses the resulting mechanical vibrations of the specimen and transforms them into electric signals.

This ensures that you are always up-to-date and saves you both time and money. This service is wstm available if you are a URL user where you do not log in with an email address. 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 Subsctiption may be the perfect solution.

The dynamic elastic properties of a material can therefore be computed if the geometry, mass, and mechanical cc1259 frequencies of a suitable rectangular or cylindrical geometry test specimen of that material can be measured.

The rod and bar geometries are described in the main body.

There is no requirement for complex support systems that require elaborate setup or alignment. This standard is also available to be included in Standards Subscriptions.

The following editions for this book are also available Specimens of these materials possess specific mechanical resonant frequencies that are astmm by the elastic modulus, mass, and geometry of the test specimen.
