Leaky Lamb waves in an anisotropic plate. II: Nondestructive evaluation of matrix cracks in fiber-reinforced composites
This paper is concerned with the use of leaky Lamb waves for the nondestructive evaluation (NDE) of damage in anisotropic materials such as fiber-reinforced composites. Two fundamental acoustic properties of the material, namely, the wave speed and attenuation have been measured. Stiffness is deduced from the wave speed. The damage mode selected for this study is matrix cracking. As expected, t...
متن کاملLeaky Lamb Waves (llw) in Multiorientation Composite Laminates
Considerable efforts have been made in recent years to develop quantitative nondestructive evaluation (NDE) techniques for composite materials, which are being used increasingly in primary structures. The leaky Lamb wave phenomenon has shown considerable potential as an NDE method [1]. Most results reported in this area to date have been concerned with unidirectional laminates [2-4]. This is at...
متن کاملCharacterization of Cohesive and Adhesive Properties of Adhesive Bonds Using Transmitted Ultrasonic Waves
The present research attempts to characterize mechanical properties, which are representative of the adhesive and cohesive states of adhesively bonded assemblies, using through-transmission immersion ultrasonic method. Transmission coefficients of an ultrasonic wave incident from different angles are measured for an assembly made of 2 substrates bonded with an adhesive. Knowing thicknesses and ...
متن کاملMeasurement of phase velocity dispersion curves and group velocities in a plate using leaky Lamb waves
The guided wave has been widely employed to characterize thin plates and layered media. The dispersion curves of phase and group velocities are essential for the quantitative application of guided waves. The technique using leaky Lamb wave (LLW) is one of the excellent methods to obtain dispersion curves. In the present work, a fully automated system for the measurement of LLW has been develope...
متن کاملTomography Applied to Lamb Wave Contact Scanning Nondestructive Evaluation
The aging world-wide aviation fleet requires methods for accurately predicting the presence of structural flaws that compromise airworthiness in aircraft structures. Nondestructive Evaluation (NDE) provides the means to assess these structures quickly, quantitatively, and noninvasively. Ultrasonic guided waves, Lamb waves, are useful for evaluating the plate and shell structures common in aeros...
