Rationale and summary of methods for determining ultrasonic properties of materials at Lawrence Livermore National Laboratory

PDF Version Also Available for Download.

Description

This report is a summary of the methods used to determine ultrasonic velocities through the many materials tested at the Acoustic Properties of Materials Laboratory. Ultrasonic velocity techniques enable the determination of material properties, including elastic moduli, without harming the materials being tested, an advantage some over mechanical methods. Ultrasonic modulus determination has other advantages as well: (1) relative ease and low cost of material preparation; and (2) comparative analysis to physical testing as a function of material loading rate dependence. In addition, ultrasonic measurement provides clues to determine grain size and orientation, and provides a relative indication of material ... continued below

Description

This report is a summary of the methods used to determine ultrasonic velocities through the many materials tested at the Acoustic Properties of Materials Laboratory. Ultrasonic velocity techniques enable the determination of material properties, including elastic moduli, without harming the materials being tested, an advantage some over mechanical methods. Ultrasonic modulus determination has other advantages as well: (1) relative ease and low cost of material preparation; and (2) comparative analysis to physical testing as a function of material loading rate dependence. In addition, ultrasonic measurement provides clues to determine grain size and orientation, and provides a relative indication of material anisotropy with respect to the material geometry. The authors usually perform ultrasonic measurements on materials in ambient atmospheric conditions, and in a relatively free-free condition. However, the authors can perform them in other environments, as required. This paper describes some of the techniques used in this laboratory and shows how ultrasonic velocities are used to establish elastic constants. It also includes a sample test report for a homogeneous isotropic solid, along with a list of references.
