1 Bone as a smart material
Bone is more than just an engineering material. Bones provide stability to our
body and are also an essential element in our mobility. Moreover bones act as
reservoirs of important minerals such as calcium. From the macroscopic point of
view there are two major types of bone tissue: the compact or cortical bone and
the trabecular or spongy bone. The shaft or diaphysis of long bones is mostly
made up of cortical bone, trabecular bone is found in the ends of bones (the
epiphyseal region) and inside short bones.
From the engineering point of view, cortical bone consists of fibers (osteons)
running in the length direction of the bone. This gives rise to mechanical
properties reflecting this transverse isotropic structure.
