APPLICATION OF THE NEW STATIC PHOTOELASTIC EXPERIMENTALHYBRID METHOD TO THE PLANE FRACTURE MECHANICS

摘要

In this research, the new static photoelastic experimental hybrid method with Hook-Jeeves numerical method has been developed: This method is more precise and stable than the photoelastic experimental hybrid method with Newton-Rapson numerical method with Gaussian elimination method.Using the new static photoelastic experimental hybrid method with Hook- Jeeves numerical method, we can separate stress components from isochromatics only, stress intensity factors can be determined and plane fracture mechanics can be analyzed.The new statics photoelastic experimental hybrid method with Hook-Jeeves should be used in the full field experiment than the photoelastic experimental hybrid method with Newton-Rapson with Gaussian elimination method
