Abstract

This report describes a flexural analog of the torsion pendulum for measuring Young's modulus and the internal friction Q factor on brittle materials. The design provides features to minimize fracture or chipping of the sample and reduces apparatus background damping so that a sample Q of >10³ can be reliably measured. Other features include strain amplitudes as low as 10^-7, small size for use in an environmental chamber, and zero static stress.
