Cracks in metalsansys finite element method analysis

Metal materials are used in machines, installations, devices or their elements, which we generally call products. The intensive use of metals in engineering designs has created many problems. Many factors such as ambient temperature, material toughness, various design errors, welding, residual stresses and fatigue cause cracks in machine elements and structures. This problem is one of the biggest problems encountered in engineering designs.In this study, propagation analysis was performed on different crack patterns formed on several different thickness structural steel plates belonging to a ship deck. For this purpose, Ansys Workbench finite element analysis method was used. Different combinations of loads were applied according to the thickness of the sample and the type of crack. The maximum tensile strength with the stress intensity factor at the corners of the determined notch on the selected sample, the resistance to breakage with the number of J integrals, the elongation amount of the notch with the number of deformations, the von-mises stresses and whether plastic deformation occurs on the sample were examined in detail with the Ansys Workbench finite element method. Figures and graphics of the studies carried out are presented in detail. Recommendations for healing are given on the sample, using existing crack repair techniques, without damaging the deck from crack growth in the metal deck plate.
