Abstract
Opterus Research and Development, Inc. proposes to develop and validate multi-scale thin-ply High Strain Composites (HSCs) constitutive modeling tools for incorporation into commercial finite element analysis codes. The constitutive models will capture the time-temperature-load-deformation viscoelastic characteristics common to HSCs as well as the yielding or permanent deformation associated with the large strains HSC materials are subjected to. The two main program components are 1) characterization of thin-ply HSCs through extensive testing and 2) multi-scale modeling of thin-ply HSCs at the constituent (matrix and fiber), lamina, and laminate levels. Of particular interest are modeling and characterizing the unique behaviors of highly spread tow woven textile HSCs. This combination of characterization and modeling will enable validated engineering tools to allow the predictive design of thin-ply HSC structures.
