“…Etches et al [28] demonstrated that substantial changes in the characteristics of bistable CFRP laminates occur when they are exposed to moisture environment. Previous studies are primarily focused on the curing process from high temperature to room temperature or thermal/ hygrothermal effect on the bistable behaviours of the asymmetric orthognal laminate [29][30][31][32]. The results show that the material properties and bistable behaviours of the laminated cylindrical shell are highly sensitive to temperature variation.…”

“…Additionally, the development of finite element method makes it possible to predict room-temperature shapes of asymmetric laminate with more complex geometry conditions [13,14]. Another interesting feature of bi-stable laminate is snap-through behavior, which was studied extensively [15,16]. Recently, the potential applications of the bi-stable laminate have received considerable attention.…”

Energy harvesting employing nonlinear systems offers considerable advantages comparing to linear systems in the field of broadband energy harvesting. Bi-stable piezoelectric energy harvesters have been proved to be a good candidate for broadband frequency harvesting due to their highly geometrically nonlinear response during vibrations. These bi-stable energy harvesters consist of bi-stable structure and piezoelectric transducers. The nonlinear response depends on the host bi-stable structure. A possible category of bistable structures is bi-stable composite laminate, which has two stable equilibrium states resulting from the mismatch in thermal expansion coefficients between plies. It has received considerable interest in deformable structure since the "snap-through" between two stable states results in a significant deformation without continuous energy supply. Combining piezoelectric transducer and the bi-stable composite laminate is a feasible method to obtain bi-stable energy harvester. Piezoelectric energy harvesters based on bistable composite laminate have been shown to exhibit high levels of power output over a wide range of frequencies. This chapter aims to summarize and review the various approaches in piezoelectric energy harvesting based on bi-stable composite laminates.

“…Dano and Hyer [7] used an approximate displacement field to calculate forces and moments for static snap-through. Cantera et al [8] modeled bistable responses including the processes of snap-through based on the Rayleigh-Ritz method. Portela et al [9] studied the bistable composite laminates, which were actuated by piezoelectric patches.…”

Global and Local Dynamics of a Bistable Asymmetric Composite Laminated Shell

As bistable composite laminated plate and shell structures are often exposed to dynamic environments in practical applications, the global and local dynamics of a bistable asymmetric composite laminated shell subjected to the base excitation is presented in this paper. Temperature difference, base excitation amplitude, and detuning parameters are discussed. With the change of temperature difference, the super-critical pitchfork bifurcation occurs. Three equilibrium solutions corresponding to three equilibrium configurations (two stable configurations and one unstable configuration) can be obtained. With the increase of excitation amplitude, local and global dynamics play a leading role successively. The global dynamics between the two stable configurations behave as the periodic vibration, the quasi-periodic vibration, the chaotic vibration and dynamic snap-through when the excitation amplitude is large enough. The local dynamics that are confined to a single stable configuration behave as 1:2 internal resonance, saturation and permeation when the excitation amplitude is small. Dynamic snap-through and large-amplitude vibrations with two potential wells for the global dynamics will lead to a broad application prospect of the bistable asymmetric composite laminated shell in energy harvesting devices.
