Bending Loads

A testing machine developed for the study of the deformational behaviour of plastics under bending loads complements high-accuracy tensile-creep testing machines and provides a more appropriate means for the testing of brittle fibre-plastics composites and plastics sandwich structures. The machine is suitable for applying constant loads and automatically recording the deflections of specimens at several points over periods of up to three months.

Compression Creep

The design and development is described of a variable load tension-compression creep machine (±50 kN) which overcomes the disadvantages of servo-hydraulic and recirculating ball screw testing machines. The use of dead weight levers to apply specimen loads ensures the achievement of low running costs. Screwed end specimens are used with a 25.40 mm parallel sided gauge length and a diameter of 12.70 mm. It is shown that, provided modest rates of loading (0.4 kN/s) are used, high accuracy ‘through zero’ loadings can be achieved. The machine has been shown to operate satisfactorily for long periods under tension-compression high temperature creep.
