dc.description.abstract | [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Fused Deposition Modeling (FDM) process is a layered prototyping technique used to build prototypes out of thermoplastic materials. It is currently only used for Rapid Prototyping. In order to use this technology for Rapid Manufacturing, Polyetherimide (Ultem 9085) was created. This material is beneficial because it has superior mechanical and physical properties when compared with the commonly used thermoplastics in the FDM process. Ultem 9085 is particularly useful for the aerospace industry due to its high strength-to-weight ratio and its FST (flame, smoke, and toxicity) rating. This thesis presents an integrated analytical and numerical approach for characterization of the Effective Composite Mechanical Properties and mesostructure of the FDM processed Ultem 9085. The developed approach uses Finite Element Analysis together with a numerical model for generation of the material mesostructure. It provides prediction of the effective composite transversely isotropic material properties and voids present in the FDM Ultem 9085 structures. The developed approach was verified experimentally. The experimental results agree well with the analytical ones. | eng |
