On the use of the GP-NARX model for predicting hysteresis effects of bolted joint structures
(2021-10-01)
Structures joined by lap-joints can present complex nonlinear dynamic behavior as a function of the stress to which the lap-joint is subjected, including contact stiffness variations and softening, along with hysteresis ...
Estudo numérico do uso de amortecedor magneto-reológico na redução de vibrações auto-excitadas durante torneamento
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Mecânica - EMec, 2022-09-27)
Chatter are self-excited vibrations that may occur during machining operations. Despite being known for more than a century, chatter is still a major limiting factor on machining operations, decreasing productivity, tool ...
A nonlinear model for multilayered rubber isolators based on a co-rotational formulation
(2017)
This article proposes a geometrically nonlinear co-rotational model aimed to characterize the mechanical behavior of elastomeric seismic isolators. The model is able to capture the axial and lateral coupling in both axial ...
