Dynamic Behavior and Sensitivity Analysis for Structural Systems with Longitudinal Mass Flow.

Nonlocal Analysis of Longitudinal Dynamic Behavior of Nanobars with Surface Energy Effect

Due to considerable stored energy in surfaces of nano-scales in comparison with the stored energy in their bulk, considering the surface energy is necessary for the analysis of various behaviors of nano-scales for more precise design and manufacturing. In this article, the longitudinal dynamic behavior of nanobars in the presence of the surface energy parameters is studied. To this end, the lon...

Sensitivity Analysis for Coupled Aero-structural Systems

M MDO OML A novel method has been developed for calculating q gradients of aerodynamic force and moment coefi% TSV cients for an aeroelastic aircraft model. This method t/c uses the Global Sensitivity Equations (GSE) to acX count for the aero-structural coupling, and a reduceda order modal analysis approach to condense the cou6 piing bandwidth between the aerodynamic and strucA rural models. Pa...

Sensitivity Analysis for Nonsmooth Dynamic Systems

Nonsmoothness in dynamic process models can hinder conventional methods for simulation, sensitivity analysis, and optimization, and can be introduced, for example, by transitions in flow regime or thermodynamic phase, or through discrete changes in the operating mode of a process. While dedicated numerical methods exist for nonsmooth problems, these methods require generalized derivative inform...
