Abstract
This paper utilized Isogeometric Analysis with the trimmed surface analysis to simulate the piezoelectric effect and the flexoelectric effect of micro-electromechanical systems (MEMS). Based on the methods, structural optimization considering circular defects was conducted in nano flexoelectric beam. Studies were made first on the theory and formulae of electromechanical mechanisms and the isogeometric analysis. Then the topology optimization based on the trimmed surface analysis was utilized in terms of defects location and defects size. The authors used Matlab to realize the above content and used the program to calculate a classical benchmark example, which comprised the basic verification of the program. Finally, the paper put up some key results in structural optimization and anticipated the further research based on this study.
