International audienceThis paper presents numerical crack propagations in case of explicit dynamics, and applied to eXtended Finite Element Method. The interest of this method is non remeshing. Hence the crack propagates through the constant mesh. Only some elements cut by the crack can have critical time step close to zero. To avoid this case, the lumping technique of mass matrix will allow to obtain the same critical time step than the case without crack: a crack and its propagation do not modify the critical time step of the whole structure. To conclude, we have $\Delta t_\text{c}^\text{X-FEM} = \Delta t_\text{c}^\text{FEM}$ for some elements.Ce papier traite de la simulation numérique de propagation dynamique de fissure dans le cas part...
