A multiaxial stress situation is created by applying compound axial forces
(tensile or compression) and torsion to allow fatigue testing of structural
materials under conditions close to actual-use conditions.

The ambient temperature for materials used in aircraft and space transfer
vehicles can extend across an extremely broad range from several tens to
several hundreds of degrees below zero at the low-temperature end to plus
several hundred to a thousand degrees at the high-temperature end.
Strength testing under the same conditions as actual operation is required to
evaluate the appropriate operational temperature range for each material.

The computer can read up to eight channels of strain gauge data synchronized
with data from the tester, such as test force, stroke, and extensometer data.
Multi-channel software permits data sampling synchronized with the load forces
by using multiple strain gauges affixed to the sample.
