An enhanced XFEM for the discontinuous Poisson problem [PDF]
Archive of Mechanical Engineering, 2019 In the paper, the extended finite element method (XFEM) is combined with a recovery procedure in the analysis of the discontinuous Poisson problem. The model considers the weak as well as the strong discontinuity.

Numerical analysis of the crack growth path in the cement of hip spacers
Fracture and Structural Integrity, 2022 The use of temporary hip prosthesis made of orthopedic cement (spacer) in conjunction with antibiotics became a prevalent method used for prosthetic infections remedy; consequently, this method makes bone cement (PMMA) more fragile.

Displacement‐Correlated XFEM for Simulating Brittle Fracture [PDF]
Computer Graphics Forum, 2020 AbstractWe present a remeshing‐free brittle fracture simulation method under the assumption of quasi‐static linear elastic fracture mechanics (LEFM). To achieve this, we devise two algorithms. First, we develop an approximate volumetric simulation, based on the extended Finite Element Method (XFEM), to initialize and propagate Lagrangian crack‐fronts ...

Fatigue life prediction of casing welded pipes by using the extended finite element method [PDF]
Fracture and Structural Integrity, 2016 The extended finite element (XFEM) method has been used to simulate fatigue crack growth in casing pipe, made of API J55 steel by high-frequency welding, in order estimate its structural integrity and life. Based on the critical value of stress intensity
