Experimental data on the onset of a so-called anomalous J/psi suppression inPbPb collisions at the SPS are considered in the framework of stringpercolation model. This onset is observed at a certain collision centrality,characterized by the number of nucleons-participants (Npart) related to theimpact-parameter. Modified Bjorken formula calculations are performed for thelocal energy densities in AA collisions at different impact-parameters and withdetailed account of the latest data available on the charged particlesdensities at midrapidity. Finally we compare variations of mean local energyand of string densities and match the occurrence of the critical percolationphenomenon with the critical energy density value, considering them at the samevalues of Npart. Similar analysis was performed for recent RHIC data and theresults are discussed.
