To precisely determine and
evaluate the mechanical properties of a material, a test system
requires the ability to measure values such as load force,
strain, crack displacement and propagation, and needs to control
with precision, the speed this parameters change.
Many variables, like load, can be measured from the load frame,
while other variables, like strain, and crack length, are
determined with higher accuracy using instruments on direct
contact to the sample, or devices that do not touch the specimen.
MTS Systems Corporation has developed
the widest line of extensometers and for the most unusual
purposes that can be offered on the market.
