Abstract (EN): The set of stress invariants (J1,J'2,¿) is very frequently employed in finite element programs for elastoplastic analysis. Some precautions are however required when computing the stress states of contact with the yield surface. The numerical problems that may arise and simple measures to avoid them are described in this paper. © 1984.
