PROBLEM TO BE SOLVED: To provide a metallic material flexure characteristic evaluation device and a metallic material flexure characteristic evaluation device capable of tracking a local flexure deformation behavior.SOLUTION: A flexure testing device 2 whose periphery is surrounded by a shading blackout curtain 2c, is used for a flexure test of a metallic material. In time series since start until end of the flexure test, a load is measured by load measurement means 2b, and displacement (stroke) is measured by displacement measurement means 3b. In addition, a deformation part of a flexure test piece 1 is imaged by an infrared ray thermography preferably, and a temperature distribution image on the flexure deformation part is imaged, and in addition, a deformation part appearance of the flexure test piece 1 is imaged by a test piece imaging device 5. The acquired pieces of data are stored in a storage arithmetic device 6, then are subjected to arithmetic processing, and the deformation behavior and temperature distribution are associated in time series and are visualized. |
