摘要
详细论述了利用三点弯曲试样测试材料动态起裂韧性的技术与发展,包括试样的选取,加载方法及动态应力强度因子的确定等。给出了计算三点弯曲试样动态应力强度因子的简单公式以及动态起裂韧性的测定方法。作者最后列出了我国目前在动态起裂韧性测试技术方面亟待研究的一些课题,并提出了自己的看法。
The dynamic initiation toughness measurement techmiqueand its development by using a three point bend speciment are presentedin detail in this paper, including specimen choice, losding method anddynamic stress intensity determination. Then, a simple formula forcalculating the dynemic stress intensity fector and a method formeasuring dynamic imitiation toughness are discribled. Finally, somepsooible research subgects connected with dynemic initiation toughnessare given.
