A finite-element-based formulation for sensitivity studies of piezoelectric systems

Sensitivity analysis is a branch of numerical analysis which aims to quantify the effects that variability in the parameters of a numerical model have on the model output. A finite-element-based sensitivity analysis formulation for piezoelectric media is developed here and implemented to simulate the operational and sensitivity characteristics of a piezoelectric-based distributed mode actuator (DMA). The work acts as a starting point for robustness analysis in the DMA technology.
