Title: Development and industrial applications of X-FEM axisymmetric model for fracture mechanics
Abstract: In this paper, an Extended Finite Element Method (X-FEM) axisymmetric model is developed and employed to compute stress intensity factors for cracked industrial specimens and components. The X-FEM model implementation is first validated by the analytical and computational stress intensity factors for penny-shaped and circumferential cracks in cylindrical bars. The validated X-FEM model is then employed to obtain the stress intensity factors for spot welds and associated kinked cracks in circular cup specimens with complex geometries. Finally, the X-FEM model is used to assess the integrity and durability of a cracked rotor coil retaining ring during the power plant operation.
