METHOD OF TESTING SPRING ACTION AND BOUNDARY PARAMETERS OF SHEET MATERIAL DURING FOUR ANGLE BENDING WITH CLAMPING OF EDGES OF SPECIMEN (VERSIONS) Russian patent published in 2009 - IPC G01N3/26 

Abstract RU 2344406 C2

FIELD: physics; test engineering.

SUBSTANCE: present invention pertains sheet stamping. Bending tests are carried out on two boards of a specimen for any angle up to 90° inclusive, leaving the edges of the specimen flat. A stamping device with dies, matrices and springs is used. The stamping device is fitted in the pressing equipment. The measuring devices are indicators, which are used for high precision measurement of linear and, after calculation, angular parameters of the specimen after unloading.

EFFECT: increased accuracy of testing.
