The Reliability Analysis for Piezoelectric Truss Structure in Consideration of Electroelastic Damage
In the piezoelectric truss structure with many random parameters under incipient defect, taking into consideration the mechanical-electric coupling effect under electric load and mechanical load, the formula of safety margins of bar have been proposed by the fracture intensity, bar section area and loads as random variables. On the base of above research, stochastic finite element method is adopted to attempt to analyze reliability of the piezoelectric truss structure. In the end, the example is given to demonstrate the influence of voltage and of damage on reliability index of the piezoelectric truss system.
