ABSTRACT: In this paper, we discuss the features of investigating the type of the critical point on the equilibrium curve (bifurcation point or limit point). There are new ideas about the completion of the initial equilibrium at the limit point or bifurcation point. Examples as the Mises’s truss, a shallow arch and a shallow cylindrical panel show the features of the birth and movement of bifurcation points along the curve of equilibrium.

KEYWORDS: bifurcation, critical point, limit point, loss of stability, nonlinear system
