The determination of elastic constants is vital for any in-depth study of material perfor mances. One of the more frequently used methods for elastic constant determination in volves ultrasonic velocity measurements. Although this method is conve

Power coefficients (Cp) and pressure distributions in the vortex tower were measured for two Tornado-Type Wind Turbine (TTWT) models (one a circular-shaped tower; the other, a spiral) in a wind tunnel and in real environments. All the maximum Cp's me

Ultrasonic inspection of thick composites has been plagued by many problems such as the high degree of anisotropy and difficulties in achieving sufficient signal penetration. The dependency of wave speed to propagation direction causes beam skewing a
