A phase-field method for modeling cracks with frictional contact
We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field method has two attractive features: (1) it can represent arbitrary crack ...

ABSTRACT This study investigates the fatigue life of AlSi10Mg alloy produced by laser powder bed fusion (LPBF) using experimental and multiscale modeling methods. A micromodel developed based on EBSD and SEM data simulates fatigue microcrack nucleation with the Tanaka–Mura model and FEM. The effects of the alloys heterogeneous microstructure, including

CSR STORAGE METHOD OF EXTENDED FINITE ELEMENT STIFFNESS MATRIX
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
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.
