Analiza rozwiązań kinematycznie dopuszczalnych dla zagadnienia naporu ścian o różnych kształtach

In the paper kinematically admissible solutions for earthmoving processes due to various buckets of loading machines are presented. On the basis of the mathematical theory of plasticity, theoretical solutions are obtained by means of the associated flow rule and the Coulomb-Mohr limit state, mass density being taken into account. Analysis of numerical solutions of several boundary problems makes it possible to draw certain general conclusions.
