STRENGTH MEASUREMENT METHOD AND TENSION OR COMPRESSION TEST DEVICE FOR PERFORMING STRENGTH MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide an efficient measurement method and measurement device in a tension or compression test device for conventionally performing measurement under a state where a test piece is subjected to thermal insulation at constant temperature.;SOLUTION: In a strength measurement method by a tension or compression test device, using two sheets of surface heating bodies 3 that are composed of a surface heating unit in which heater elements are provided in a surface fashion and a magnet plate integrated on a rear surface of the surface heating unit and in which an electrode of an end of the surface heating unit is provided with a power source cord, measurement is performed in a state where a test piece is interleaved by the surface heating unit and a temperature controller connected with the power source cord keeps the test piece warm at constant temperature.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
