DEVICE TO MEASURE CROSSWISE AND LENGTHWISE DEFORMATION OF ELASTOMERIC MATERIALS Russian patent published in 2011 - IPC G01B11/16 

FIELD: physics.

SUBSTANCE: proposed device comprises system of specimen material clamps, loading and straining mechanism, measurement pickup made up of computer mouse rigidly coupled with coiled edge straightener pointer that may move across, along and about tested specimen, and recording unit. Recording unit comprises computer to convert straightener pointer travel into lengthwise and crosswise deformation, contraction ratio, conditional Poisson factor and allow visualising travel of said pointer on monitor and version results. Loading and straining mechanism is made up of spaced apart current conducting buses, one representing moving bus. Note here that said busses are connected with computer by aforesaid mouse.

EFFECT: higher accuracy and automatic measurements.
