“…Researches (Li et al, 2020; Luo et al, 2012; Nam et al, 2008; Pomyai et al, 2021; Promsawat et al, 2017c; Shindo et al, 2017) on the effects of external influences have mainly considered the influence of the electric field and temperature and analysed the fatigue behaviour of piezoelectric ceramics under different conditions. For example, Shindo et al (2017) carried out dynamic fatigue experiments on piezoelectric ceramics with cracks under the joint influence of an electric field and low temperature.…”

The fatigue behaviour of a piezoelectric ceramic stack co-fired at low temperatures under the influence of a large cyclic dynamic load was studied. The piezoelectric ceramic stack is equivalent to a parallel plate capacitor with a charge source in parallel. The equations for the total current, output current and capacitor charging current of an equivalent device for an applied load were derived using Kirchhoff’s theoretical formula. A new type of fatigue test equipment was developed for continuous long-term M-shaped wave output. The piezoelectric ceramic stack is positioned between two concrete slabs, forming a pavement-subgrade piezoelectric structure. The fatigue behaviour of the piezoelectric ceramic stack was observed for 800,000 cycles of dynamic load. The results show that the dynamic load studied produced fatigue damage in the piezoelectric ceramic stack. As the number of dynamic loads increased, the electric output capacity of the piezoelectric ceramic stack decreased. Evident stage divisions were observed in the fatigue behaviour of the piezoelectric ceramic stack under cyclic dynamic loading. The electric output capacity of the stack decreased as the number of dynamic loads increased in the early and late stages, whereas it exhibited negligible change during the stable period.

“…The initiation and propagation of crack in ferroelectric material is accompanied by the microstructure evolution of polarization domain morphologies [3]. Such an electromechanical coupling property makes the fracture behaviors of ferroelectric materials rather complex.…”

This paper is devoted to the L p (p > 1) solutions of one-dimensional backward stochastic differential equations (BSDEs for short) with general time intervals and generators satisfying some non-uniform conditions in t and ω. An existence and uniqueness result, a comparison theorem and an existence result for the minimal solutions are respectively obtained, which considerably improve some known works.Some classical techniques used to deal with the existence and uniqueness of L p (p > 1) solutions of BSDEs with Lipschitz or linear-growth generators are also developed in this paper.
