The static and dynamic regimes of the bistable asymmetric cross-ply composite laminated plates

AbstractFor the static and dynamic regimes of the bistable asymmetric cross-ply composite laminated plates, the theoretical model and the finite element model (FEM) are established. The 2D and 3D diagrams for the supercritical pitchfork bifurcation, which are dominated by the length, the width, the aspect ratio, the ratio of side to thickness, the number of layers and the temperature difference, can be used to describe the static regimes. The restoring force curves (RFCs) and the potential energy curves (PECs) are shown. The single-well vibration, the limit-cycle oscillations, the multiple-period snap-through, and the chaotic snap-through are the dynamic regimes that predominate.Keywords: Static and dynamic regimesbistable asymmetric cross-ply composite laminated platesthe theoretical modelthe supercritical pitchfork bifurcationsnap-through AcknowledgmentsThis work was supported by National Natural Science Foundation of China (Grant numbers 12102031, 12102207, 12272189 and U2241264), Young Talents of Science and Technology in Universities of Inner Mongolia Autonomous Region (Grant number NJYT23022) and Inner Mongolia Natural Science Foundation (Grant number 2023MS01014).Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
