Description and Specification for Lab Tenders
Astra Scientific Elastic Properties of Deflected Beam Apparatus with Data Acquisition.
Description:
An experimental apparatus to investigate the practical plastic bending of beams.
The experiment hardware fitted a Structures Test Frame. Students fix a specimen beam in chucks at both ends of a backboard. The chucks can either clamp the beam, or hold it on a knife-edge. The students then load the beam using a screw mechanism and electronic load cell.
The load cell connects to a Digital Force Display, which displays the load as the beam deforms. A long-travel digital deflection indicator on the backboard measures specimen deformation. To compensate for the specimen shortening as it deforms, one of the chucks moves along the backboard, relative to the deformation.
To apply a load until the specimen beam is in the fully plastic condition, that is, the beam has undergone plastic collapse. Compare the beam behavior with theoretical predictions based on traditional yield stress theory.
The Operation Manual provides details of the equipment including sample experiment results.
The Operation Manual describes how to use the equipment and gives experiment procedures.
