Description
The Servo-Pneumatic Four Point Bend Apparatus stand-alone features a pneumatic actuator which is digitally controlled by a pneumatic servo-valve to provide accurate loading in both stress and strain control modes. In addition, the Servo-Pneumatic Four Point Bend Apparatus features a beam cradle which has been designed to four point bending with backlash free rotation and horizontal translation of all load reaction points.
Controlling the Four Point Bend Apparatus stand-alone is the Integrated Multi-Axis Controls and Data Acquisition System (IMACS).
The Four Point Bend Apparatus can be used as part of your Superpave performance based testing program
