New applications for composite materials are being developed at a rapid pace. However, their complex microstructures present considerable challenges for nondestructive testing and characterization. Ultrasonic waves provide quantitative means of nondestructive evaluation of these materials and structures. For this purpose, it is necessary to obtain a clear understanding of the characteristic...

Biography

Subhendu K. Datta

The authors present fundamental equations and their solutions for plane wave propagation in an infinite homogeneous anisotropic elastic material. … A systematic investigation of the effect of different fiber layups and increasing number of laminae on the dispersion characteristics reveals features that are useful for experimental determination of lamina properties. … Comparison with some available experimental results shows good agreement between the model results and observations.
