The Servohydraulic Instron 8501Mechanical Testing Machine

The Instron 8501 testing machine can be used to obtain Stress/Strain curves in both tension and compression, and also fatigue data when used with a cyclic waveform.

The force applied to the sample is measured with a Load Cell (strain gauge balance) on the stationary top cross-head.
The bottom cross-head holds the hydraulic
actuator which loads the sample.

The material deformation is determined from either the moving grip position or by means of a strain gauge extensiometer.

The machine is operated via the Control Panel or the computer. Data may be collected and displayed during acquisition using the MAX software of the computer.
