Limit Analysis with the Dual Aane Scaling Algorithm

The collapse state of a rigid plastic material with the linearized Mises yield condition is computed. We use an infeasible point variant of the dual aane scaling algorithm for linear programming which is extremely eecient for this large sparse and ill conditioned problem. For a classical test problem we obtain better results than previously, both for the limit load and for the collapse elds, thus setting a new standard for computations in limit analysis.
