ABSTRACT:
Disclosed is a device for measuring lateral deformation in an material spmen which includes a generally ring shaped frame member displaced generally perpendicularly to the object being measured. The frame member itself comprises a first and a second generally arc shaped element which abut end to end. At least one spring arm member is fixed at one end on a mounting projection on the first arc shaped element and its movable end abuts a spring receiving projection from the second generally arc shaped element. Strain gauges are fixed to the spring arm member to detect changes in the flexture of the spring arm member resulting from relative movement of the two arc shaped elements which results from lateral deformation of the material specimen. A linear variable differential transformer having a lateral projection is also mounted on one of the arc shaped elements. The lateral projection bears against a reaction arm mounted on the other of the arc shaped elements to measure small deformations which may not be sensed by the strain gauges on the spring arm members.
