Abstract
In this work, a numerical simulation and experimental results using a modified prism technique are presented. It is based on pulse-echo technique and involves the measurement of both longitudinal and transversal waves velocities in trapezoidal-prism shaped specimens with only one transducer. Both longitudinal and transversal waves are generated through mode conversion at the interface between water and the specimen under test. Based on numerical simulation with the 2-D Elastodynamic Finite Integration Technique (EFIT), several snapshots are generated to illustrate the functionality of this new technique, and the experiment was performed on cement paste with various water/cement ratios.
