In this paper. the nonlinear oscillations induced by friction in a ball-on-socket system are investigated. The nonlinear time response was obtained by solving the differential equations of the friction-noise model of the finite element ball with multiple modes. The different patterns of motion were analyzed via the bifurcation diagram. https://www.markbroyard.com/flash-pick-weleda-skin-food-75ml-online-sale-flash-save/
