Eight-node membrane element (M3D8 and M3D8R)

These elements are similar to the S8 and S8R shell elements, respectively, except that they cannot sustain bending. This is obtained by modelling hinges in each of the end nodes of the elements. Apart from that, all what is said about the S8 and S8R elements also applies here with one exception: instead of the *SHELL SECTION card the *MEMBRANE SECTION card has to be used.
