Claims

[Scope of utility model registration request]

By inserting a tension pin into the two holes of a compact tension specimen having two holes and a notch between them and applying a test load in opposite directions, strain is generated at the tip of the notch. , ASTM to determine plane strain fracture toughness of materials
In the compact tension test equipment specified by the standard, the hole diameter of the compact tension test piece is
The dimensions are larger than those specified in the TM standard, and the large-diameter hole has a flange surface that is press-fitted to the surface of the compact tension test piece so as to be able to transmit a test load, and a hole that is perpendicular to the flange surface. Insert the cylindrical part of a jig with a cylindrical part, insert a tension pin into the hole of the jig, apply the test load from the tension pin to the jig, and from the jig to the compact tension test piece surface. A compact tension testing device characterized by transmission.
