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 ...

Modelling localised fracture of reinforced concrete structures [PDF]

open access: yes, 2016
This paper presents a robust finite element procedure for simulating the localised fracture of reinforced concrete members. In this new model the concrete member is modelled as an assembly of plain concrete, reinforcing steel bar and bond-link elements ...

A fully coupled finite element framework for thermal fracturing simulation in subsurface cold CO2 injection

open access: yesPetroleum, 2018
Thermal fracturing could occur during cold CO2 injection into subsurface warm rock formations. It can be seen in a variety of fields such as carbon geo-sequestration, unconventional gas development, enhanced oil recovery, geothermal energy extraction ...

The ALE-method with triangular elements: direct convection of integration point values [PDF]

open access: yes, 2000
The arbitrary Lagrangian-Eulerian (ALE) finite element method is applied to the simulation of forming processes where material is highly deformed. Here, the split formulation is used: a Lagrangian step is done with an implicit finite element formulation,

X-SFEM, a computational technique based on X-FEM to deal with random shapes [PDF]

open access: yes, 2007
International audienceWe propose a new method to deal with random geometries. It is an extension to the stochastic context of the eXtended Finite Element Method. This method lies on two majors points: the implicit description of geometry by the level set

A Cell-Based Smoothed XFEM for Fracture in Piezoelectric Materials

open access: yesAdvances in Materials Science and Engineering, 2016
This paper presents a cell-based smoothed extended finite element method (CS-XFEM) to analyze fractures in piezoelectric materials. The method, which combines the cell-based smoothed finite element method (CS-FEM) and the extended finite element method ...

Interaction Analysis of Non-aligned Cracks Using Extended Finite Element Method

open access: yesLatin American Journal of Solids and Structures
Multiple flaws are frequently occurred in actual components, such as pressure vessels and power plants. These flaws will in some circumstances lead to more severe effects than single flaw alone.

ANALYSIS THE FORMULA OF STRESS INTENSITY FACTORS FOR THE COMPACT TENSION SHEAR TEST

open access: yesJixie qiangdu, 2021
The Compact Tension Shear( CTS) specimen proposed by Richard is a commonly test type used in mixed ModeI/II loading. The formula of stress intensity factors( SIFs) for the CTS test has already given by relevant literature.
