ABSTRACT
The ability of ultrasonic waves to travel in a web direction over a minimum time for composites was advanced by the author in 1966.1 This effect can be used for different applications in composites, ceramics, and metal alloys.2,3 Nondestructive evaluation (NDE) of the material properties of a structure makes this method very useful. Research has been conducted to determine the modulus of elasticity of high-speed turbine blades.4 In this research, a general nondestructive test method for deterring the modulus of elasticity in different directions was examined.
