This paper analyzes the effects of acoustoelasticity and damages on propagation of ultrasonic waves in fiber-reinforced plastics. Acoustoelasticity is used for nondestructive evaluation of the internal stress of materials. The technique utilizes the speed shift of ultrasonic waves due to nonlinearity of the elastic characteristics. When a fiber-reinforced plastic is subjected to a strong load, microdamage may be caused, for example, fiber failure, matrix cracking, and matrix yielding. Thus, propagation of ultrasonic waves in such composite materials depends not only on the stress but also on the microdamage in the materials. This paper presents the constitutive equation of fiber-reinforced viscoelastic materials with damage based on damage mechanics. The effects of microdamage and stress on the speeds of ultrasonic longitudinal waves are examined in the acoustoelastic test for high-polymer composite material, PBT, reinforced with glass fiber
