| description abstract | We have studied a nonlinear springmass chain loaded by a quasistatic pull. The spring forces are assumed to be cubic with intervals of negative stiffness. Depending on the parameters, the system has multiple equilibria. The normal form and the bifurcation behaviors for the singleand twodegreeoffreedom systems are studied in detail. A new type of bifurcation, which we refer to as a star bifurcation, has been observed for the symmetric twodegreeoffreedom system. This bifurcation is of codimensionfour for the undamped case and codimensionthree or two for the damped case, depending on the form of the damping. | |
