Abstract: This paper presents a numerical procedure for accurate determination of a limit or a bifurcation point. The method minimizes simultaneously the first and the second variations of an admissible functional or iterates to satisfy the equilibrium and the semi-definite condition for the tangent stiffness matrix. It can be readily incorporated into a computer program for non-linear finite element analysis to improve its accuracy in the location of critical points.
