Abstract
A material testing apparatus includes an actuator to apply a force to a load head according to electronic control signals. The load head supplies a load to a material specimen in a first dimension. A plurality of load line displacement (LLD) reference points extend radially outward from the load head; and a plurality of LLD measuring devices correspond to the plurality of LLD reference points. Each LLD measuring device is positioned to detect a position of a corresponding LLD reference point along the first dimension and is configured to transmit position signals to a controller programmed to perform a performance test on the material specimen using feedback control based on a combination of the position signals, including an average of the position signals.
