Dynamic load cell apparatus

A load cell for use in dynamic testing apparatus for mechanically testing samples includes an accelerometer mounted in the load cell on the same axis as the line of action of the mechanical force applied to the specimen under test. The resultant signal from the combination of the normal output from the load cell and the output from the accelerometer compensates for errors introduced by the mass of the moving grip used to grip the specimen in the apparatus.

Bi-axial electromagnetic actuator

A biaxial electromagnetic actuator for a materials testing apparatus comprises a first electromagnetic actuator for imparting a linear force to an output shaft and a second, direct drive electromagnetic actuator for imparting a rotational force to the shaft. The shaft is mounted in two combination bearings which permit the shaft to move axially and rotationally. One of the bearings is located within a hollow cylindrical member which constitutes the armature of the direct drive actuator in order to provide a compact and symmetrical arrangement.

Testing of samples

Test apparatus comprising means for holding a sample to be tested, means for altering the strain in the sample, an optical arrangement for monitoring the sample to be tested, and processing means for processing the signals resulting from the monitoring of the sample under test, wherein the environment between the optical arrangement and the sample under test is controlled, and wherein the sample to be tested is located in a position external to the controlled environment.
