This book presents a modern and unconventional introduction to
anisotropy. The first part presents a general description of Anisotropic
Elasticity theories while the second part focuses on the polar
formalism: the theoretical bases and results are completely developed
along with applications to design problems of laminated anisotropic
structures. The book is based on lectures on anisotropy which have been
held at Ecole Polytechnique in Paris.
