Simulation, Entwurf und Regelung von piezoelektrischen und leichten, intelligenten Strukturen basierend auf der Methode der Finiten Elemente

摘要

A finite element based computational framework for the virtual design and simulation of smart lightweight structures is presented.A new piezoelectric composite shell element is derived from nonlinear 3D continuum mechanics and a modified Hu-Washizu functional of the coupled electromechanical problem. Based on the state space model, a design process including closed-loop control is presented which is also applicable to prestressed membrane structures.
