ABSTRACT:
A strain gage extensometer used for measuring uniaxial and biaxial strains in material test specimens. The extensometer is composed of two independent axial strain measuring sensors joined together by a resilient member which is instrumented to provide transverse strain data. All compliant, instrumented members are coupled to the deformations of the specimen, which thus causes strain in the instrumented members which is sensed by suitable strain gages and instruments. A special attachment mechanism is provided by the thin, parallel elements machined into one of the sensors.
