Abstract:

This program investigates acoustic emission techniques for nondestructive evaluation of the integrity of a boron-aluminum composite material. The influence of biaxial states of stress upon the acoustic response of the composite material is examined through implementation of a test program which utilizes the off-axis tensile coupon specimen. Both mechanical property and acoustic emission test results are presented. Author
