摘要
运用云纹干涉法的波前干涉原理和非接触测量面内位移方法,测试三点弯曲试件裂纹嘴张开位移,并将此方法用于高温断裂韧度测试中。经过大量的金属材料断裂韧度测试,建立一套线弹性、弹塑性断裂韧度非接触测试方法,解决高温环境下的断裂韧度测试。
The research is mainly about using the wave front interference principle of Moiré interferometry and non-contact measuring the inside plane displacement and about the open displacement for crackle-mouth of three-spot crooked specimens. This kind of measuring is used in tincture toughness in high temperatures. By measuring the fracture toughness of many kinds of metal, a new good way has been developed for non-contact measuring for fracture toughness of elastic and elastic-plastic property.
