Title:
PUNCH FOR BENDING RESISTANCE PERFORMANCE EVALUATION TEST, AND TESTING METHOD OF BENDING RESISTANCE PERFORMANCE EVALUATION
Document Type and Number:
Japanese Patent JP2023072461
Kind Code:
A
Abstract:
To devise a shape of a punch so as to be capable of simply generating an axial collapse and a bending buckling for an evaluation component.SOLUTION: A punch 12 applies push-in a load in a longer direction of an evaluation component 1, when there is the evaluation component 1 whose one end part in a longer direction is fixed and the other end part in the longer direction is a load input side end part 1A, to the load input side end part to evaluate bending resistance performance of the evaluation component 1 made of a metal longer direction component against an axial load. A counterface surface 10A facing the other end part in the longer direction comprises: an initial abutting face 10Aa which is orthogonal to the push-in direction or approximately orthogonal thereto; an inclined face 10Ab which is continuous to the initial abutting face 10Aa and heads to a direction opposite to the push-in direction as going apart from the initial abutting face 10Aa; and a deviation constraint face 10Ac which heads to the push-in direction as going apart from the inclined face 10Ab.SELECTED DRAWING: Figure 2
