Development of a Computational Framework for Aeroelasticity of Geometrically Nonlinear Structures: A Partitioned Coupling Approach

High Altitude Long Endurance (HALE) configurations have gained much popularity in the recent past. Although, HALE aircraft enable efficient and environmental-friendly flying, they necessitate a large Aspect-Ratio wing. These slender structures are prone to large, non-linear deformations which further increase the unsteady nature of aerodynamic...

Stacking Sequence Retrieval of Large Composite Structures in Bi-step Optimization Strategies Using Mechanical Constraints

Multi-step optimization of large composite structures involves formulating the stiffness distribution in terms of lamination parameters that provide a continuous design space, followed by a second optimization in the discrete design space to obtain equivalent stacking sequences. The retrieval of stacking sequences is often challenging as a...
