Abstract:
1. An apparatus for simultaneously measuring longitudinal and shear wave speeds in materials under load comprising: a rigid housing with a long axis, a body substantially parallel to the long axis with an exterior surface and an interior surface, an open end, a closed end substantially opposite the open end with a hole in the closed end extending through the interior surface and the exterior surface, the closed end substantially perpendicular to the long axis, and a housing exit port in the body of the rigid housing extending through the interior surface and the exterior surface; a spacer residing inside the rigid housing, the spacer having a spacer specimen side and a spacer transducer side substantially parallel to the spacer specimen side, the spacer substantially larger than the hole in the closed end of the rigid housing, the spacer further contacting the interior surface of the rigid housing such that the closed end of the housing is in contact with the spacer specimen side; a load transferring body fitting substantially inside the rigid housing, the load transferring body having an exterior, the entirety of the exterior of the load transferring body making substantially close contact with the interior surface of the body of the rigid housing, the load transferring body further having a transducer hole extending fully through the load transferring body and substantially parallel to the long axis of the rigid housing, the load transferring body further having a load transferring body exit port extending from the transducer hole fully through the load transferring body; an ultrasonic transducer fitting substantially inside the transducer hole of the load transferring body; and a transducer depressing mechanism, the transducer depressing mechanism securing the ultrasonic transducer against the spacer transducer side.
