Fig. 6. General representation of transducer placement and rotatable turntable used by Markham
Fig. 8. Figure (a) documents the experimental arrangement as used by Smith, figure (b) documents the mode conversion process allowing both alongitudinal and shear wave to propagate through the sample when incident waves strike the surface at oblique angles
Fig. 9. Documenting thetransverse wave at 90° toUltrasonic elastic constants of carbon findings from Smith that a close relationship to the theoretical is recorded using the C44 value obtained from propagating a fibre direction
Fig. 11. Figure (a) documents the transverse wave with the solid line being theoretical predictions, figure (b) documents the longitudinal wave,which may be observed to deviate away from Musgrave predictions towards rotated Young’s Modulus values
