International audienceThe advances of material characterization by means of imaging techniques require powerful computational methods for numerical analyses. This paper focuses on the advantages of coupling the X-FEM and level sets to solve microstructures with complex geometry. The level set information is obtained from a digital image and then used within a X-FEM computation, where the mesh does not need to conform to the material interface. An example of homogeniza-tion is presented.La caractérisation des matériaux est en progrès constant, ce qui implique un niveau de développement similaire des méthodes numériques utilisées. Ce travail présente une application de la méthode X-FEM couplée aux level-sets pour la résolution de problèmes de...
