Abstract Tensile and compressive tests are the most common mechanical tests performed on materials. Tensile-Compression test machines normally consist of screw driven beams which can be moved at a range of operator chosen constant speeds. A load cell is mounted on the beam and, with the use of a pair of grips, a sample is fixed between the load cell and a fixed base plate. As the beam moves the force on the sample is recorded by the load cell and the strain measured using an extensometer. Test machines are available in a wide variety of sizes and from numerous manufacturers. Screw driven machines can operate in the strain rate range 10−5 to 1s−1. Higher strain rates can be achieved using hydraulically operated machines (up to 10 s−1). Even higher rates (102 and above) require the use of specialised equipment such as drop-weights or Hopkinson bars.
