Abstract: This paper describes a technique for computing optimal upper bound slopes stability factors based upon the Linear Matching Method. The method assumes a perfectly plastic material which obeys the Drucker-Prager yield criterion and its associated flow rule and involves the sequential matching of an appropriate linear material to the yield function. The basic concepts are described and the convergence of this method is guaranteed whether the real material is matched to a compressible or incompressible linear material. The process converges to the least upper bound associated with the class of displacement fields when implemented in a finite element method. Comparison with published solutions illustrates the accuracy and feasibility of the proposed method for a simple homogeneous slope stability problem.
