Lee, J. S. and Santamarina, J. C. (2006). "Discussion to the paper by Leong, E.C., Yeo, S.H., and Rahardjo, H. Measuring Shear Wave Velocity Using Bender Elements." Geotechnical Testing Journal, Vol. 29, No. 5
The authors present a valuable summary of common bender element installations and data interpretation approaches, including new data on input signal effects (wave form, amplitude, and frequency). The purpose of this discussion is to contribute complementary information gathered through our own experience which is directly related to bender element installation and measurements. Wave propagation phenomena such as geometry dispersion, material dispersion, relative scale effects, and low-pass Brillouin filtering are discussed in Santamarina et al. (2001).
