摘要
为研究材料在高速变形时的性态和破坏过程以及热力偶合问题,作者自行研制并设计了一套红外瞬态测温装置,同时对它进行了整体动态标定.并利用该装置在摆锤式杆-杆型冲击拉伸试验机上首次获得了三种不同材料的试件在冲击拉伸过程中的瞬态温升曲线,得到了一些颇有意义的结论。
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.
