- Materials And Their Applications
- Mechanical Properties- how a material reacts to an external force
- Compressive Strength- the ability to withstand being crushed or shortened by pushing forces
- Tensile Strength- The ability to resist stretching or pushing forces
- Bending Strength- the ability to resist forces that may bend the material
- Shear Strength- the ability to resist sliding forces on a parallel plane
- Torsional Strength- the ability to withstand twisting forces
- Hardness- the ability to resist abrasive wear such as scratching
- Toughness- the ability to absorb impact force without fracture
- Plasticity- the ability to be permanently deformed and retain the deformed shape
- Ductility- the ability to be drawn out under tension, thereby reducing the cross-sectional area without cracking
- Malleability- the ability to withstand deformation by compression without cracking
- Elasticity- the ability to be deformed and then return to the original shape when the force is removed
- Physical Properties- the structure of a material
- Density- mass of the material in a standard volume of space
- Fusibility- the ability of the material to be converted from a solid to a liquid by heat
- Good fusibility is essential for a metal being cast
- Magnetism- the natural force between objects that causes the material to attract iron or steels
- Corrosion/degradation resistance-the ability of the material to withstand environmental attack and decay
- Electrical Properties
- Electrical Conductor- allows the flow of electrical current through the material
- A good conductor gives little resistance to the flow of charge
- Electrical Insulator- Does not allow the flow of electricity through the material
- Electrical Conductor- allows the flow of electrical current through the material
- Thermal Properties
- Thermal Conductor- allows the transfer of heat energy through the material
- Thermal Insulator- Prevents the transfer of heat through the material
- Thermal expansion- the increase in material volume in response to a heat input
- Optical Properties
- Opaque- Prevents light from travelling through
- Translucent- allows light through but diffuses the light so that objects appear blurred
- Transparent- allows light to pass through easily
- Mechanical Properties- how a material reacts to an external force
