Abstract

A commercial single crystal silicon material has been investigated for use as an elastic modulus reference material using the impact excitation method. The results show good consistency between the three samples tested, and a very close to the literature data for silicon. The average flexure-derived data supplied with the material are also close to the results in the current study, but the scatter/uncertainty of the former is much greater than that achieved using the impact excitation method.
This work has enabled indirect validation of the impact excitation system as well as providing confidence in the use of this material for other purposes, such as beam flexure and dynamic mechanical analysis (DMA).
