    Description :
    _____________

    The TRESCA operator calculates the Tresca equivalent stress for
 a stress field.


      Contents :
      __________


      SIG1  : stress field (MCHAML type, CONTRAINTES subtype)
              
      CAR1  : field of geometrical properties required for the
              thin shells (MCHAML type, CARACTERISTIQUES subtype)

      MOT1  : key word indicating for the shells where the calculation
              of the stresses is requested :

              'SUPE'  : on top layer
              'MOYE'  : on the mid-surface (by default)
              'INFE'  : on bottom layer

      CHAM2  : Tresca equivalent stress (MCHAML type, SCALAIRE
               subtype)


      Note :
      -------

    For thin shells, a true Tresca stress is calculated
 from generalized stresses.
