Abstract: A general method for simultaneously measuring longitudinal and shear wave speeds in materials under load via echo or transmission is described. This process proceeds in simple steps. Users load a specimen, either compressionally, tensilely, or torsionally and the loading is directed along a loading axis. Users connect a transducer with the specimen without loading the transducer and connect the transducer with a data collection apparatus.

The user measures signals on the data collection apparatus, allowing the user to calculate longitudinal wave speeds and shear wave speeds, whereby both longitudinal wave speeds and shear wave speeds of specimens under load can be measured simultaneously using one transducer. A novel device for measuring longitudinal and shear wave speeds in materials simultaneously is also described.

Abstract: There is disclosed a high pressure sensing header which is relatively insensitive to mounting torque. Essentially the header consists of an outer torque isolating shell which has a “C” shaped cross section with the cylindrical shell surrounding an inner “H” section header. The inner “H” section header has a thick diaphragm and is surrounded by the torque isolating shell which is secured to the “H” section header at a peripheral flange of the “H” section header.
