Fracture Modelling of a Cracked Pressurized Cylindrical Structure by Using Extended Iso-Geometric Analysis (X-IGA)

open access: yesMathematics, 2021
In this study, a NURBS basis function-based extended iso-geometric analysis (X-IGA) has been implemented to simulate a two-dimensional crack in a pipe under uniform pressure using MATLAB code.

Coupled Finite Volume Methods and Extended Finite Element Methods for the Dynamic Crack Propagation Modelling with the Pressurized Crack Surfaces

open access: yesShock and Vibration, 2017
We model the fluid flow within the crack as one-dimensional flow and assume that the flow is laminar; the fluid is incompressible and accounts for the time-dependent rate of crack opening.

eXtended finite element methods for thin cracked plates with Kirchhoff–Love theory [PDF]

open access: yes, 2010
A modelization of cracked plates under bending loads in the XFEM framework is addressed. The Kirchhoff–Love model is considered. It is well suited for very thin plates commonly used for instance in aircraft structures.

Stefan Problem through Extended Finite Elements: Review and Further Investigations

open access: yesAlgorithms, 2009
A general review of the extended finite element method and its application to the simulation of first-order phase transitions is provided. Detailed numerical investigations are then performed by focusing on the one-dimensional case and studying: (i ...

Time-independent hybrid enrichment for finite element solution of transient conduction–radiation in diffusive grey media [PDF]

open access: yes, 2013
We investigate the effectiveness of the partition-of-unity finite element method for transient conduction–radiation problems in diffusive grey media. The governing equations consist of a semi-linear transient heat equation for the temperature ?eld and a ...

An extended HDG finite element method for convection-diffusion-reaction equation interface problems

open access: yes四川大学学报. 自然科学版, 2023
This paper proposes an extended hybridizable discontinuous Galerkin (HDG) finite element for the 2D and 3D convection-diffusion-reaction equation interface problems on body-unfitted meshes. This finite element uses piecewise polynomials of degrees k (k≥1)
