Résumé : We study Vlasov dynamics for the self-gravitating sheet model. Numerical simulations of the Vlasov equation are carried out in order to determine the energy distribution function (EDF) resulting from an initial waterbag situation. The prediction of the EDF by Lynden-Bell statistics as proposed by Yamaguchi (Yamaguchi, Phys. Rev. E 2008) is then checked, separating the core from the tail of the EDF.
