MODIFICATIONS TO AN AXIAL TENSION TESTER FOR BRITTLE MATERIALS

A REDESIGN OF THE AXIAL TENSION TESTER HAS PRODUCED A MORE COMPACT, EASIER TO USE SYSTEM WHILE STILL MAINTAINING ALL THE FAVORABLE FEATURES. THIS DEVICE EFFECTIVELY MINIMIZES THE PARASITIC BENDING STRESS NORMALLY ASSOCIATED WITH THE CONVENTIONAL TENSION TEST. ADDITIONALLY, THE SPECIMEN DESIGNED FOR USE IN THE ORIGINAL DEVICE WAS REDESIGNED TO REDUCE THE OVERALL SIZE AND TO INCORPORATE A CONSTANT DIAMETER GAGE SECTION. A PLASTIC MATERIAL (HYSOL CP5-4290), WHICH WAS READILY AVAILABLE AND WHICH EXHIBITS THE BRITTLE CHARACTERISTICS DESIRED, WAS CHOSEN AS THE SPECIMEN MATERIAL TO BE USED IN THE TEST PROGRAM CONDUCTED TO PROOF TEST THE DEVICE AND SPECIMEN DESIGN. TESTS WERE ALSO CONDUCTED TO DETERMINE THE LOAD-ERROR EFFECT OF THE O-RINGS WITH THE INTENT OF ESTABLISHING A LOAD CALIBRATION PROCEDURE. /AUTHOR/
