The proposed procedure is based on the Bennett's algorithm and applies to nonlinear structural analysis by the finite element method. The appropriate computational cost analysis is included and states the conditions of the economical use of the method. Affiliations:| Kleiber M. | - | IPPT PAN | | Lutoborski A. | - | IPPT PAN |
