Finite Element Quadrature of Regularized Discontinuous and Singular Level Set Functions in 3D Problems [PDF]
, 2012 Regularized Heaviside and Dirac delta function are used in several fields of computational physics and mechanics. Hence the issue of the quadrature of integrals of discontinuous and singular functions arises.

Study of Stress Intensity Factor in Corrugated Plate Using Extended Finite Element Method (XFEM) [PDF]
Engineering and Technology Journal, 2016 The presence of crack with different lengths and locations in structure of corrugated plate is studied. XFEM is along with enrichment function based on partition of unity is used for the calculation of stresses due to the presence of crack.

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 ...

An extended finite element method with smooth nodal stress [PDF]
, 2013 The enrichment formulation of double-interpolation finite element method (DFEM) is developed in this paper. DFEM is first proposed by Zheng \emph{et al} (2011) and it requires two stages of interpolation to construct the trial function.

A CutFEM method for two-phase flow problems
, 2018 In this article, we present a cut finite element method for two-phase Navier-Stokes flows. The main feature of the method is the formulation of a unified continuous interior penalty stabilisation approach for, on the one hand, stabilising advection and ...

A PDE-constrained optimization formulation for discrete fracture network flows [PDF]
, 2013 We investigate a new numerical approach for the computation of the 3D flow in a discrete fracture network that does not require a conforming discretization of partial differential equations on complex 3D systems of planar fractures.
