The quasi-static problem is formulated in terms of rates. The traditional Euler method is reviewed. A new approach is developed for the quasi-static bifurcation analysis. Bifurcation is said to occur when there exists at least one additional, distinctive rate of change of a configuration in equilibrium. The related variational theorem is derived in the same manner that the Sanders variational theorem for creep was developed. An example is given for the creep buckling of a thin-walled cylindrical shell loaded in axial compression. It is concluded that the new method yields good approximate solutions but is apparently simpler than the Euler method.
