Based on the theoretical background, the formulation for the three‐dimensional elasto‐plastic analysis has been enhanced and implemented in the computer program. The algorithm utilities the initial stamen approach to satisfy the material non‐linearity. The discrimination inculpates the continues and the discontinuous boundary elements. Also included are the domain cells with the linear and quadratic approximation. The non‐linear boundary element results are presented to demonstrate the accuracy and usefulness of the method.
