Slump has often been correlated with the yield stress of concrete as defined by the Bingham model. The discussion is still open as to what the yield stress value actually is and how to measure the yield stress of a suspension in general and for a

On Lamb Modes as a Function of Acoustic Emission Source Rise Time

January 1, 2010
Author(s)
Marvin A. Hamstad
A study was carried out to examine Lamb-wave modal content as a function of the acoustic emission (AE) source rise time. The study used a validated finite element code to model the source operation and subsequent wave propagation up to a distance of 480 mm
