DISCUSSION ON "DESIGN, MANUFACTURE AND PERFORMANCE OF A LATERAL STRAIN DEVICE" BY EL-RUWAYIH, AA

A lateral strain caliper for automatically measuring the change in diameter of uniaxial and triaxial test specimens is described. The caliper opening is bridged by a miniature water-submersible displacement transducer of the inductance type. The caliper is positioned around the middle of the test specimen which is lightly held by two pads fixed on the inside of the caliper. The pads are located on opposite ends of the diameter normal to that passing through the hinge. Any change in diameter of the test specimen causes a corresponding amplified change in the caliper opening which is continuously measured by the transducer. On monitoring 100 mm diameter test specimens on a three-figure indicator, lateral strains of the order of 0.005% may be discerned. /TRRL/
