| Popis: | A parametrically driven structural model based on Mindlin–Reissner plate theory is developed to capture the threedimensional deflections of a compliance-based morphing trailing edge device with severe structural discontinuities. The model is used to study the Fish Bone Active Camber (FishBAC) device, which is represented as a discontinuous plate structure that captures the step changes in stiffness created by the concept’s geometrical configuration. Courant’s penalty method is implemented in the form of artificial penalty springs to account for stiffness discontinuities. A numerical validation is performed using finite element analysis, followed by experimental validation under actuation loads. This analytical model represents a robust, efficient, mesh-independent, and parameter-driven solution tomodeling discontinuous plate structures. These traits make it useful for ongoing fluid–structure interaction analysisand optimization of the FishBAC concept and also for application to other complex composite structures. |
