RESIDUAL STRESS FILTERING OF PHOTOELASTIC IMAGES BASED ON IMPROVED ANISOTROPIC METHOD

摘要：

　　Dynamic photoelastic imaging technology is an important means to observe the ultrasonic stress field inside a solid.However,the sample will generate residual stress during the manufacturing process,which will cause some interference to the observation.In this paper,the iterative formula diffusion coefficient in the anisotropic algorithm is improved according to the characteristics of residual stress in the photoelastic image,and compared with the original algorithm,the improved algorithm is more conducive to filtering out the residual stress background in the image.
