On Some Problems in Determining Tensile Parameters of Concrete Model from Size Effect Tests
Polish Maritime Research, 2019 The paper presents results of numerical simulations of size effect phenomenon in concrete specimens. The behaviour of in-plane geometrically similar notched and unnotched beams under three-point bending is investigated.

Cell Agglomeration Strategy for Cut Cells in eXtended Discontinuous Galerkin Methods
International Journal for Numerical Methods in Engineering, Volume 126, Issue 9, 15 May 2025.ABSTRACT In this work, a cell agglomeration strategy for the cut cells arising in the eXtended discontinuous Galerkin (XDG) method is presented. Cut cells are a fundamental aspect of unfitted mesh approaches, where complex geometries or interfaces separating subdomains are embedded into structured background grids to facilitate the mesh generation ...

CRACK INFLUENCE ON A PIPE WITH DOUBLE SLOPE UNDER INTERNAL PRESSURE: NUMERICAL SIMULATION WITH XFEM
International Islamic University Malaysia Engineering Journal, 2020 This work analyses the effect of elliptical cracks on a pipe with double slope thickness transition, using the extended finite element method (XFEM), level sets were defined to describe the three-dimensional (3D) cracks.

CSR STORAGE METHOD OF EXTENDED FINITE ELEMENT STIFFNESS MATRIX
Jixie qiangdu, 2019 The extended finite element method（ XFEM） is one of the most widely used numerical methods to deal with cracks,holes and inclusions. Based on the partition of unity method（ PUM）,the additional function terms are introduced to the displacement ...

XFEM appliquée aux structures aéronautiques
, 2017 Dans le domaine des structures primaires aéronautiques, la tolérance aux dommages devient un critère de plus en plus dimensionnant. Basé essentiellement sur des méthodes analytiques ou modèles numériques simplifiés, la levée de conservatismes de calcul et la rapidité d’obtention de scénarios critiques deviennent limitant.
