Abstract

This paper presents the constitutive modeling of the viscoplastic response of triaxially braided composites. The constitutive model is determined through use of the Multiscale Generalized Method of Cells and considers three length scales in the analysis. The micro, meso, and macroscales are analyzed and the constituent constitutive model, fiber/tow repeating unit cell, and triaxial braid repeating unit cell are modeling at each length scale respectively. Results are presented for the in-plane tensile, compressive, and shear responses at various strain rates. Results show good correlation with available experimental data.
