Mechanical model of the arterial collagen considering waviness and preferred direction of collagen fibers

Mechanics of soft tissues, e.g. arterial wall, has important contributions on their biological function. These mechanical behaviors are mainly governed by their fibrous microstructure. Collagen is a fibrous protein which has a considerable share on mechanical load-bearing of the soft tissues. Hence this contribution is dedicated to propose a strain energy density function which account for orientation and waviness of these fibers. Such a model is very beneficial in modeling all kind of biologic soft tissues and especially cardiovascular soft tissue.
