The following page of notes will cover:
- Physical characteristics (Physical properties)
- Mechanical characteristics (Mechanical properties)
Electrical conductivity:
The Property that lets electrical current flow through a material
Thermal conductivity:
The Property that lets thermal energy flow through a material
Biodegradability:
A material's ability to break down over time as a result of biological activity (being broken down by microorganisms)
Chemical resistance:
A material's ability to withstand chemical attack without being broken down
Corrosion resistance:
A material's ability to withstand rusting from water without being broken down
Strength (Tensile, Compressive, Torsional, Shear, Bending):
The ability allowing a material to resist forces from all directions (compressive, tensile, bending, shear, torsional).
Elasticity:
The ability allowing an object or material to reassume its normal shape after being stretched or compressed.
Placticity:
A material's ability to be permanently deformed and retain its deformed shape
Malleability:
A materia's ability to be deformed by compression without being torn / cracked.
Ductility:
The ability of a material to be drawn/stretched out thin (usually into wires)
Hardness:
A material's ability to withstand indentation / abrasion / scratching.
Toughness:
A material's ability to absorb impact force without fracture.
Durability:
A material's ability to withstand wear, pressure, and damage.
