Abstract
An example material testing system includes: a crosshead configured to be actuated to transfer testing force to a test specimen during a material test; an actuator configured to actuate the crosshead and to apply the testing force to the crosshead; a force sensor configured to measure force applied by the crosshead to the specimen; and a control processor configured to: determine a reference force range based on a first force measurement from the force sensor in response to initiation of movement of the crosshead; and in response to a second force measurement by the force sensor that is outside of the reference force range, controlling the actuator to apply a braking force to the crosshead.
