Overview of modeling workflow for both FE models proposed under uniaxial compression. (A) Experimental analysis of fibre reinforced hydrogels mechanical behavior under uniaxial compression to access material properties and validate numerical predictions. (B) Continuum FE model of idealized composite architecture. Only a quarter of the composite construct was modelled with the reinforcing box scaffolds idealized as thin laminas (defined in a local coordinate system) embedded in a hydrogel matrix. At the fibre scaffold interconnections a truss element was added with its longitudinal axis in the global y-direction. (C) Micro-FE model of the real composite architecture at different deformation levels. Real architecture was accessed at increasing levels of compactaction with the use of a micro-compression device, as schematically represented, and a high-resolution CT scanner.
