文摘
NURBS elements are successfully employed to model the flexoelectric effect in dielectrics. Topology optimization of flexoelectric micro and nanostructures can enhance their energy conversion efficiency. An efficient design methodology based on a combination of isogeometric analysis (IGA), level set and point wise density mapping techniques is presented. The point wise density mapping is directly used in the weak form of the governing equations and its derivative is consistently derived using adjoint sensitivity technique.
