Szukana fraza: [Abstract = "The case of sensitivity of a bifurcation point is under development \(see \(Mróz and Haftka, 1994\) for more details\). An arc\-length algorithm embedded in the optimization algorithm is built. These modifications introduce numerical problems which occur at limit points \(Doedel et al., 1991\). All systems are very stiff and the quadratic convergence of the Newton\-Raphson algorithm is lost, so higher\-order derivatives with respect to state variables have to be computed \(Wriggers and Simo, 1990\)."]
