International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

Convergence Investigation of XFEM Enrichment Schemes for Modeling Cohesive Cracks
Mathematics, 2022 When simulating cohesive cracks in the XFEM framework, specific enrichment schemes are designed for the non-singular near-tip field and an iteration procedure is used to solve the nonlinearity problem.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.ABSTRACT Wave propagation effects such as resonance and interference effects complicate the design of many acoustic devices, particularly when the dimensions of the device are in the order of the operating wavelength. At the same time, these complications also offer an opportunity for numerical optimization schemes to outperform designs achieved using ...

Mixed Integration Scheme for Embedded Discontinuous Interfaces by Extended Finite Element Method
Frontiers in Earth Science, 2022 The extended Finite Element Method (XFEM) is derived from the traditional finite element method for discontinuous problems. It can simulate the behavior of cracks, which significantly improves the ability of finite element methods to simulate ...

Finite Element Analysis of FRP Debonding Failure at the Tip of Flexural/Shear Crack in Concrete Beam [PDF]
, 2013 One of the most common failure modes of strengthened RC beams with externally bonded FRP is intermediate crack (IC) debonding of FRP initiated at the tip of flexural/shear cracks. This study presents a method, using extended finite element method (XFEM),

Improving the modified XFEM for optimal high‐order approximation [PDF]
International Journal for Numerical Methods in Engineering, 2019 SummaryThis paper investigates the accuracy of high‐order extended finite element methods (XFEMs) for the solution of discontinuous problems with both straight and curved weak discontinuities in two dimensions. The modified XFEM, a specific form of the stable generalised finite element method, is found to offer advantages in cost and complexity over ...
