Shear deformation characteristic evaluation method, evaluation device and test piece for shear deformation characteristic evaluation

摘要

PROBLEM TO BE SOLVED: To provide a shear deformation characteristic evaluation method, an evaluation device and a test piece for shear deformation characteristic evaluation, which can obtain highly accurate shear deformation evaluation characteristics. SOLUTION: A flat surface portion 101 is connected to a test piece 100 via a flat surface portion 101, and a first restraint surface 102 and a second restraint surface 103 which are connected to the flat surface portion 101 and are inclined with respect to the flat surface portion 101 are formed. The first range straddling the first restraint surface 102 and the second restraint surface 103, and the second range straddling the flat surface portion 101, the first restraint surface 102 and the second restraint surface 103 and adjacent to the first range, are formed into a flat surface portion. A wall portion 106 is formed between the first range and the second range by moving the wall portion relatively in parallel in the displacement direction inclined with respect to 101, and the first range and the second range are moved in parallel in the displacement direction. A method for evaluating shear deformation characteristics, in which the wall portion 106 is shear-deformed by flowing a material from the second range toward the wall portion 106, and the shear deformation characteristics of the shear deformation portion 107 of the wall portion 106 are evaluated.
