Tensile Test of Metallic Material by Strain Rate Control Using an Automatic Extensometer

When the international standard for tensile testing of metallic materials, ISO 6892, was revised in 2009 and the corresponding Japanese Industrial Standard, JIS Z 2241, was revised in 2011, a strain rate control method (measurement of strain with an extensometer) was added as a test item in addition to stress rate control as a method for loading materials to their yield point. Accompanying these changes, requests for tensile tests of metallic materials by strain rate control are now increasing. A highly accurate extensometer is necessary when conducting strain rate control. The Shimadzu SIE-560SA automatic extensometer makes it possible to measure the elongation of hard materials such as metals and soft materials such as plastics with high accuracy over a wide range. Measurements of the elongation can be conducted over the entire region from the start of the tensile test to fracture (rupture), and automatic attachment/detachment of the extensometer arm to the test piece and automatic setting of the gauge length are also possible. This article introduces an example in which the possibility of conducting ISO 6892-1:2019 compliant strain rate control was verified using a Shimadzu Autograph AGX™-100 kNV precision universal testing machine and an SIE-560SA automatic extensometer.
