Abstract

Methods for determining the dynamic and static elastic constants (E, G, and ..nu..) of engineering materials were developed and evaluated. A hybrid sonic method incorporating the double pulse, block-sample technique for determining accurate room-temperature data and the single pulse, thin-wire technique for gathering elevated-temperature data were used to determine the dynamic elastic constants. Of three methods examined for measuring static constants (using the linear variable differential transformer, the weldable resistance gage, and the capacitive gage), the method employing the linear variable differential transformer gage served well as a reference method for dtermining Young' modulus. The method using the capacitive gage showed greatest merit for determining combined E, G, and ..nu... The dynamic and static elastic constants of 2 1/4 Cr--1 Mo steel, types 304- and 316 stainless steel, and alloy 800H were determined from room temperature to 649/sup 0/C (1200/sup 0/F) and higher.
