Popis: A general methodology for the determination of the effective behavior of architectured materials endowed with a discrete structure at the microscopic scale is presented. It relies on the discrete homogenization method to derive the effective mechanical properties from the topology of the material and the properties of the micro constituents. This methodology is presently applied to textile monolayers modelled as a network of undulated and interwoven beams representing the yarns in the fabric. The initially discrete fabric architecture is represented at the mesoscopic level by an anisotropic micropolar effective continuum. The effective mechanical properties are validated by FE simulations performed over a representative unit cell.
