並列タイトル等Fracture Behavior Observation of Wall-thinned Pipes by Image Strain Measurement System
一般注記this paper describes fracture behavior evaluation of wall-thinned pipes by image processing strain measurement system. Regular grids with nominal size of 10 x 10 mm were marked on the 100A carbon steel pipes and the images taken with 6 CCD cameras of 15 million pixcels were correlated to realize resolution of 0.3% strain. Strain of the cylinder outer surface was evaluated by I) modeling the grids as a cylindrical shell, 2) measuring deformation of the grid on a projected plane, and 3) by applying updated Lagrangian method. The results indicate that the method is effective for analyzing fracture modes and fracture criterions.
