| dc.description.abstract | The constraint impact is the most important factor in structural integrity evaluations aspects on crack tip fracture mechanics to accurately anticipate the stresses condition of material under the influence of crack. This thesis investigates a stress field changes along the thickness and around the angle of the crack-tip. Through modification of the analytical formulas proposed using HRR-J-∆𝜎, the two-dimensional parameter method can be extended to analyse the three-dimensional elastic-plastic crack-tip field. The intermediate stresses are developed to shows the stresses state along the crack tip through the constraint loss parameter, 𝛼. The results from HRR-J-∆𝜎 technique is shown along the crack tip, the hoop and radial stresses vary along the crack tip between 0 ≤ 𝛼 ≤ 1 and in the angular range 0° ≤ 𝜃 ≤ 180°. A series of analytical expression have been developed to characterize 3-D elastic-plastic crack-tip fields. This will allow researcher to be able to map crack-tip stress field in structures and allow a direct assessed of structural integrity in an efficient and quick approach. | en_US |
