Abstract
The present work deals with the calculation of effective elastic properties for a periodically laminated composite considering nonuniform imperfect adhesion. The effective properties for two- and three-layers composites with imperfect and perfect interfaces respectively are calculated via Finite Element Method (FEM) and analytical technique based on the two-scale Asymptotic Homogenization Method (AHM). Thus, it is used two-layers model with imperfect interface conditions (spring type), as well as three-layers model with perfect conditions, where an interface model is proposed for the computation of the interphase properties. Numerical simulations are provided to illustrate graphically the effective properties. The effects of the nonuniform imperfection on the effective properties are observed. When the thickness of the interphase is very small, the three-layers composites behave like two-phase composites
