An Infrared Transient Temperature Measuring Apparatus and Its Application to the Tensile Impact Testing
红外瞬态测温装置及其在冲击拉伸试验中的应用

To investigate the fracture behavior with thermal coupling for materials at high speed deformation. An infrared transient temperature-measuring device is designed and maunfactured. After being calibrated dynamically, it is used in experiments with a pendulum testing machine of bar-to-bar tensile impact type. The transient temperature rising curves of three sample materials are obtained in fracture test for the first time. Some meaningful conclusions are drawn.
