Numerical and experimental investigation of the structural behavior of a carbon fiber reinforced ankle-foot orthosis

Highlights • A multiscale modeling strategy for both UD and textile CFRP is proposed. • The resulting macromechanical model accounts for the intrinsic micro- and meso-structure of the material. • The material model is validated on different scales against experimental data. • Finally, a numerical an...

Description
Summary:Highlights • A multiscale modeling strategy for both UD and textile CFRP is proposed. • The resulting macromechanical model accounts for the intrinsic micro- and meso-structure of the material. • The material model is validated on different scales against experimental data. • Finally, a numerical and experimental investigation of an AFO is performed. • The comparison shows good agreement of local and global values.
