摘要
对裂纹尖端每一级等差线条纹环取３种读数，采用射线法（级数展开）进行具体计算，在适当选择范围内，能更精确测定ＫⅠ、ＫⅡ值图２，表２。
The stress intensity KⅠ,KⅡ can be accuratly determined in a proper selected range through concrete calculation on three kinds data, taken from every equidifferent stripe on the crack point by the ray method(series expansion).2figs.,2tabs.,2refs.Key works ray method,stress intensity factor,equidifferent stripe
