Abstract
In this paper, the mechanical output and electrical output of the piezoelectric cantilever beam under the inverse piezoelectric condition has been studied. The limit state equation for the mechanical reliability and electrical reliability of the piezoelectric cantilever beam under the inverse piezoelectric effect has been derived. The reliability of the piezoelectric cantilever beam has been predicted by using the principle of the series system with inverse piezoelectric. The proposed reliability model of the piezoelectric cantilever beam under the inverse piezoelectric state is simple, which is obtained by using the first-order second-moment method. It has been shown that the proposed model is robust and practical with validation by an engineering problem.
