Description

Several ultrasonic wave mechanics models which are based on the effective elastic properties of the overall fiber reinforced composites are currently being used in the industry and academia. Due to the repetition of the ply orientation and the lay-up sequence traditionally used in the industry, these models which often “smear” the individual ply elastic properties to obtain effective elastic properties of the entire composite. [1,2] This is an acceptable approximation for long wave length waves propagation in homogeneous or quasi-homogeneous ply lay-ups media and has provided useful results in the non-destructive evaluation process.
