Effective properties of centro-symmetric micropolar composites with non-uniform imperfect contact conditions (Q6093852)

The authors apply the homogenization theory to three-dimensional linear micropolar composite materials with centro-symmetric constituents. The imperfect contact conditions are modeled like a generalization of the spring model, where tractions and coupled stresses are continuous, but displacements and microrotations are discontinuous across the interface. Local displacements and micro-rotations on the periodic cell are found and used to find the effective coefficients for two-layered composites.
