ABSTRACT:
An apparatus for simultaneously measuring longitudinal and shear wave speeds in materials under load via echo or transmission is described. The apparatus comprises a housing with an open end, a closed end opposite the open end with a hole in the closed end, and a housing exit port. A spacer resides inside the housing, the spacer having a spacer specimen side and a spacer transducer side. A load transferring body having a transducer hole fits inside the housing and contacts an interior surface of the housing. An ultrasonic transducer fits inside the transducer hole of the load transferring body. A transducer depressing mechanism secures the ultrasonic transducer against the spacer transducer side, whereby users can simultaneously measure longitudinal and shear wave speeds of specimens inserted into the hole in the closed end of the housing and contacting the spacer.
