Zusammenfassung: | It is an object that a strain state of a bending outside surface of a test specimen is photographed by use of a camera without falling out of focus during a bending test. A bending test facility for a metal sheet material for an automobile body includes a supporting member (1) that supports two supported portions (2) of a flat test specimen (P) formed of the metal sheet material for an automobile body, a punch (4) for performing a bending test in which an area between the two supported portions (2) of the test specimen (P) is pressed from an opposite side to the supporting member (1) so that the test specimen (P) is bent to be deformed, and a camera (5) for photographing, from the side of the supporting member, a bending outside surface of the test specimen (P) during the bending test using the punch (4), with relative positions of the punch (4) and the camera (5) during the bending test being fixed. |
