- Abstract
-
A correction for the errors due to load un1t deflection ls presented and examples are given that show the effectiveness of the correct1on on typical data.
Displacement errors are typically induced through deflections of the load cell, extension rods, and fixtures, with the load frame contributing a very small
effect. With this correction, forced vibration test systems can be used over a wide range of frequencies, amplitudes and temperatures to give accurate material dynamic characterization data for specimens in shear, ompression,
tension, or bending with minimal changes in specimen geometry or fixtures. Work so far has been conducted on metallic samples. Work remaining includes collection of data on samples to be included in the Damping Technology round robin. - Description
