Abstract

The present invention provides a testing system of metal sheet, and the system at least comprises a clipping apparatus, a hydraulic press apparatus and a measuring apparatus. The clipping apparatus comprises a first mold, a second mold and a hyperelastic plate. The hydraulic press apparatus connects to the clipping apparatus and transfer a hydraulic pressure via the second mold to the one of the testing sheet set to let it bulge along an orientation toward the first mold. The measuring apparatus connects with the clipping apparatus and the hydraulic press apparatus separately to measure a momentary pressure of the hydraulic pressure and the bulge height of the one of the testing sheet set. A testing method using the abovementioned system is also disclosed in the present invention.

Claims7

Dependent claims

The testing system of metal sheet for integrating the testing for a plurality of mechanical properties of metal sheet, comprising:

a clipping apparatus having a first mold, a second mold and a hyperelastic plate, wherein the first mold and the second mold being capable for clipping one of a testing sheet set of a metal sheet, and the hyperelastic plate being detachable disposed between one of the testing sheet set and the second mold;
a hydraulic press apparatus connecting to the clipping apparatus and transferring a hydraulic pressure via the second mold to the one of the testing sheet set to let the testing sheet set bulge along an orientation toward the first mold;
and
a measuring apparatus connecting with the clipping apparatus and the hydraulic press apparatus separately to measure a momentary pressure of the hydraulic pressure and a bulge height of the one of the testing sheet set.
