    Description:
    ------------

    This procedure enables the user to perform elastic and plastic
 buckling calculations.

    Contents :
    __________

    TAB2 : object (TABLE type) which must be composed of :

   1) If you use the new objects MMODEL and MCHAML

      Index    Pointed object          Contents
                  type
                  
      'OBJM'     MMODEL           model object
      'LAM1'     FLOTTANT         minimum multiplying coefficient
      'LAM2'     FLOTTANT         maximal multiplying coefficient 
      'NMOD'     ENTIER           number of requested eigen modes
      'CLIM'     RIGIDITE         matrices associated with the restraints

    Then, the user has a choice between :

      'SIG1'     MCHAML           stress field varying with   
                                  the load multiplier                 
     ('SIG0')    MCHAML           stress field which does not
                                  vary with the load multiplier
      'MATE'     MCHAML           material properties

     ('CARA')    MCHAML           geometrical properties


    or :

      'RIGI'     RIGIDITE         stiffness matrix
      'KSIG'     RIGIDITE         geometrical stiffness matrix



    TAB1 :  object (TABLE type) containing as many tables as 
            there are calculated modes, and indexed by the number
            of the mode.
            Each table associated with a mode contains :

      Index    Pointed object           Contents
                   type

      'LAMB'    FLOTTANT      load multiplying coefficient 
      'DEPL'    CHPOINT       standard eigen mode
      'MODN'    ENTIER        Fourier's harmonics number
      'MODM'    ENTIER        azimuthal mode number


    Note :
    ________

    For a Fourier's series analysis, the buckling may be
 searched from a family of harmonics providing in TAB2 :

      'MODE'    LISTENTI      List of Fourier's harmonics

    In order to define the boundary conditions, the following
 option will have to be used  :

                     OPTION FOURIER NOHARM ;


    A plastic buckling analysis may be performed giving :

      'PLAS'    MOT           word requesting the plastic buckling
      'MATP'    MCHAML        tangential plastic material (see MOTA)


    The method used is that of the tangential modulus.
 The user may also supply the requested tangential matrix as stiffness
 matrix ('RIGI' index) if he does not wish to use this method.
