    Notes: The problem of the critical height of a vertical cut in a purely cohesive medium has been repeatedly dealt with by several authors and, in spite of its apparent simplicity, the characterization of satisfactory solutions has presented, for a considerable period, notable difficulties. The present paper supplies the results obtained with a numerical method, which has so far been applied successfully to a considerable number of problems.

    A mixed formulation and mixed finite elements for limit analysis (1982)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: A mixed variational principle for the limit analysis of rigid-perfectly plastic continua is discussed, in which the nonlinear yield condition and the associated flow rule appear through a suitably defined ‘penalty’ function. A mixed finite element discrete formulation is derived and a sequential unconstrained minimization technique is devised, affording a complete (static and kinematic) solution. Several results are presented in both structural and soil mechanics, compared with previously available (exact and numerical) solutions.
