[en] This report is the continuation of a former report about incompressible structures in statics. Its essential purpose is to derive the mass matrix of the triangular tor element based on Herrmann's formulation. A special focus is brought on the problem of teh condensation of the pressure d.o.f.'s. Examples are presented, in order to assess the correct working of the program. In one of these, details are given on the approprate way of condensing the pressures in the incompressible case. Finally, chapter 4 is devoted to the problem of the convergence of pure displacement models to the correct solution when Poisson's ratio converges to 0.5.
