Abstract
A postulated thermodynamic relation for elastic solids which equates
the stress dependence of thermal expansion to the temperature dependence
of reciprocal Young's modulus has been tentatively verified in
earlier work by Rosenfield and Averbach (J. Ap. Phys., 27, 2 (195>6)).
This thesis describes experiments which were intended to extend this
verification, but which succeeded only in verifying quite closely
the results obtained earlier for the temperature dependence of the
reciprocal Young's modulus. Experimental techniques utilizing a
high temperature Tuckerman optical strain gage instead of the wire
resistance strain gages employed by the earlier authors are described,
and the difficulties encountered in their use are discussed.
