Abstract : The goal of the research was to develop a new methodology for the fabrication and the design of new multifunctional composites and devices using 3D printing. The main accomplishments of this project can be summarized as follows: 1) Proposing and demonstrating the 4D printing concept and novel printed active composites (PACs); 2) developing multiple PAC continuum mechanics PAC models of various levels of accuracy and complexity; 3) developing the 4D printing concept to design PACs undergoing multiple shape changes; 4) developing a PAC-based concept that enables reversible shape changes; 5) application of PACs for printed origami design; 6) developing a finite element framework for the optimum design of PACS by topology optimization; 7) optimizing and experimentally characterizing PACs that undergo desired shape changes.
