The homogenization of composite beams is based on the fact that inelastic defects of the material produce additional fields of strains that are equivalent to eigenstrains in an identical but elastic background beam with effective virgin stiffness. Mathematically, a multiple field approach of the elastic background results. Since beam theories deal with stress and strain resultants, it is important to define proper resultants of these eigenstrains, i.e. inelastic curvatures and inelastic averaged shear angles.
