摘要：
This paper presents the development of a methodology for the determination of the stress intensity coefficients K1 and K2 from the absolute path-difference patterns (APD) in an example of a plate with an oblique crack. The methodology assumes the construction of graphs of the numbers of the fringes in the APD patterns along the crack axis. The SIC determination was performed on an universal holographic test stand.
