| Summary: | account for the presence of rigid body rotation and algorithm. Each evaluation method included both opening and and aluminum. The analyses of the finite element models conclusively demonstrated. could be used to determine the fracture parameters, such as density film grating (80 lines/mm) suitable for use in determine the opening and shear mode fracture parameters, determine the shear mode stress intensity factor with developed combines a series representation of the crack-tip displacement equations with the method of local collocation displacement field due to mixed mode loading. The algorithm geometric moire experiments and to develop an algorithm which geometric moire experiments, which were conducted on both P geometric moire tests were used to test the validity of the indicated that the algorithm developed could be used to input data. The geometric moire experiments, using 80 intensity factor with reasonable accuracy. The ability to line/mm gratings, demonstrated that the algorithm could be mixed mode loading, with and without rigid body rotation. numerical experiments demonstrated that the determination of patterns. Finite element modeling, numerical experiments, and sufficient accuracy using geometric moire was not The 80 line/mm film gratings were successfully used for the the fracture parameters was influenced by the accuracy of the the stress intensity factor, associated with a crack-tip There were two objectives in this research: to develop a high to calculate the fracture parameters. The algorithm can also translation which are often present in experimental moire used successfully to determine the opening mode stress without being affected by the rigid body rotation. The |
