INVESTIGATION OF SECOND ORDER ELASTIC PROPERTIES OF VARIOUS MATERIALS

摘要

The finite elastic theory of Monahan was applied to the problem of calculating dilatational and shears velocities through solids as a function of hydrostatic pressure and simple axial stress. Experiments were performed on three materials: polystyrene, Armco iron, and Pyrex glass. The results of the theory were checked within experimental error, and three constants appearing in Monahan’s theory were determined for these three materials.
