Abstract

En 中文

• A novel concurrent topology optimization approach is proposed for structural energy flow control. • Objective functions and sensitives targeting energy flow focusing, barrier, and circulation are established. • The Poynting vector is utilized for accurately characterizing structural energy flow. • Random morphology description functions are employed to generate initial design guesses. • Various bi-scale plate designs demonstrating effective manipulation of energy flow are presented.
