Why study long-term failure?. Because bones fail by long-term mechanisms as a result of strenuous exercise. Failures that occur in this way are called Stress Fractures' by clinicians, to distinguish them from fractures that occur due to trauma (e.g. a fall). Stress fractures occur often in athletes

Structure of long bone

Structure of long bone. Bone contains neatly arranged matrix of protein (collagen) fibers along with water and mineral salts (calcium hydroxide & calcium phosphate). The mineral salts accumulate in-between and around the collagen fibers, they crystallize and the tissue hardens.

Mechanical Properties of Polymers

Mechanical Properties of Polymers P olymers as materials need to be "strong" or "tough" or even "ductile". How can we define these Mechanical Properties ? How do we measure how "strong" a polymer is? What is the difference between a "strong" polymer and a "tough" one ?
