FEA-based Design of Continuum Structures for Optimal Dynamic Properties

Continuum structures need to be designed for optimal vibrational characteristics in various fields. Recent developments in the finite element analysis (FEA) and numerical optimization methods allow creating more accurate computational models, which favors designing superior systems and reduces the need for experimentation. In this talk, I will present my work on FEA-based optimization of thin shell structures for improved dynamic properties where the focus will be on laminated composites. I will initially explain multi-objective optimization strategies for enhancing load-carrying and vibrational performance of plate structures. The talk will continue with the design of curved panels for optimal free and forced dynamic responses. After that, I will present advanced methods that I developed for modeling and optimization of variable-stiffness structures. Finally, I will outline the state-of-the-art techniques regarding numerical simulation of the finger in contact with surfaces and propose potential research directions.
