Abstract

A series of internal-pressure failure tests of steel thin-walled cylindrical shells (vessels) is carried out to measure the crack growth rate in the course of breaking current-conducting strips. The experiments use a specially designed measuring setup based on a precision converter of the signals from resistance thermometers and Terkon thermocouples interfaced with a computer. The crack velocity is measured during straight-line crack propagation and crack branching.

钢中裂纹分支率的实验确定

摘要

进行了一系列钢薄壁圆柱壳(容器)的内压破坏测试,以测量在破坏导电条的过程中的裂纹扩展速率。实验使用了一种特殊设计的测量装置,该装置基于电阻温度计和与计算机连接的Terkon热电偶的信号的精确转换器,基于精确的转换器。在直线裂纹扩展和裂纹分支过程中测量裂纹速度。
