JIG FOR ANTI-BUCKLING OF SPECIMEN

摘要

A jig for preventing bending of a specimen is provided to measure Bauschinger's effect from a deformation rate caused in a stamping process and thus to evaluate the mechanical property of the specimen with high precision. A jig for preventing bending of a specimen comprises a pair of jigs(20) which are attached to a specimen(1) to guide the specimen, and two pairs of auxiliary jigs(30) which are formed on both sides of the jigs to move. The jig is composed of a longitudinal member(21) attached to the specimen in the longitudinal direction, and one or more transverse members(22) connected to the longitudinal member and attached to the specimen in the width direction.
