Abstract
A simple procedure for accurate calculation of pore pressures in undrained elasto‐plastic materials is described. An 8‐node element is used, with ‘reduced’ integration during stress redistribution, and ‘full’ integration to form the global stiffness matrix for the modified Newton—Raphson procedure. An analysis of passive earth pressure in an undrained soil is used to demonstrate the algorithm and computed results are compared with a closed‐form solution.
