In mechanical and pneumatic conveying systems, the material generally moves or slides in direct with the trough, casing and other components of the machine. Mechanical properties can be determined by conducting experimental test on the material . MECHANICAL PROPERTIES: The properties of material that determine its behaviour under applied forces are known as mechanical properties. The need for better understanding and more detailed characterization of mechanical properties of tissue engineered, as well as native heart valve constructs is thus evident. BMME- Biomaterials-Lecture:- Mechanical Properties of Biomaterials. Mechanical properties of biomaterials For any material to be classified for biomedical application there are many requirements must be met , one of these requirement is the material should be mechanically sound; for the replacement of load bearing structures, the material should possess equivalent SS-316L has established itself as the best available bio implant material. Specific Heat: Specific heat is a property that tells which material gets heated very quickly. Abstract: Almost all metallic biomaterials are crystalline, with regular atomic arrangement, and their mechanical properties are dominantly controlled by dislocation motion and twinning closely. Definitions 6 Biomaterial • A natural or synthetic material that is suitable for introduction into living tissue.1 • A synthetic material used to replace part of a living system or to function in intimate contact with living tissue.2 • A biomaterial is a substance that has been engineered to take a form which, alone or a a part of a complex system is the mechanical properties of a biomaterial can best be described by its modulus of elasticity, ultimate tensile strength, elongation to failure, and fracture toughness.
