Description
MTS Criterion™ Series 60 Product Manual Introduction 17
When performing a tensile test, the specimen is held by appropriate grips in the
tension space, and the actuator goes up to move the table and the upper crosshead
upward, while the lower crosshead keeps still. This way, tensile load is applied
on the specimen. While tensile load is applied to the specimen, the sensors
measure the load applied, the displacement, and the specimen extension. The
controller handles all the outputs from the sensors and then transfers to the
testing software, and the software provides the results and reports accordingly.
The principle described above also applies to compression test; the only
difference is that the specimen is put between the lower crosshead and the table,
and as the actuator goes up, compressing load is applied on the specimen. If you
have flexural/bend fixtures or shear fixtures, bending/flexural or shearing test can
be done in the compression space.
The lower crosshead is only for adjusting the tensile and compression
spaces.
Applying load on the specimen by adjusting the crosshead position can
cause equipment damage.
Do not apply load by the lower crosshead.
All tests should be performed by moving the actuator.
