Elastic behaviour of multiply coated fibre-reinforced composites

摘要: This work is devoted to the derivation of elastic strain and stress fields in an infinite medium constituted n-layered transversely isotropic cylindrical inclusion, surrounded by a matrix subjected uniform conditions at infinity. From these results, average are calculated each phase inclusion. These averages used order estimate overall moduli heterogeneous fibre-reinforced materials. Christensen Lo's energy condition for three-phase model extended this case shown be equivalent (or stress) condition. Whereas method yields new transverse shear modulus, four other proved given coincident Hashin-Rosen bounds n-C.C.A. can derived recursive algorithm.
