Abstract:
1. A tensile test method, suitable for performing a tensile test on a specimen by a tensile test fixture, wherein the tensile test fixture comprises: a base; a pull bar, comprising a position limiting member, a specimen-fixing member and a shaft member, wherein the shaft member is connected between the position limiting member and the specimen-fixing member, wherein the specimen is adopted to be fixed between the -base and the specimen-fixing member; and a forcing member, having a cavity and an opening connected with the cavity, wherein the shaft member passes through the opening, and the position limiting member is located within the cavity, a dimension of the position limiting member is larger than a dimension of the opening so that the position limiting member is not separated from the cavity, the forcing member is adopted to pull the position limiting member of the pull bar to perform a tensile test for the specimen, the tensile test method comprising fixing a specimen between the base and the specimen-fixing member of the tensile test fixture; and pulling the forcing member to allow the forcing member to contact the position limiting member with a speed, and stretching the specimen between the base and the specimen-fixing member, wherein the speed is larger than zero.
