1.1 Mechanical & Physical Properties of Materials Flashcards
(29 cards)
Compressive Strength
The ability to withstand being crushed or shortened by using forces (compression).
Tensile Strength
The ability to resist stretching or pulling forces (tension).
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 from applied torque or torsion.
Hardness
The ability to resist abrasive wear such as scratching, surface indentation or torsion.
Toughness
The ability to absorb impact force without fracture.
Plasticity
The ability to be permanently deformed (shaped) and retain the deform shape.
Ductility
The ability to be stretched into a thin shape without breaking
Malleability
The ability to withstand deformation by compression without cracking; malleability increase with a rise in temperature.
Elasticity
The ability to be deformed and then return to the original shape when the force is removed.
Density
The 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, usually by heat. Good fusibility is an essential property 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 environment attack and decay.
Manufactured board
A man-made, wood based composite material
Stock form
The set of standard sizes in which materials are available, as well as the format
Mechanical properties
Associated with how a material reacts to an external force
Composite
A material comprised of two or more different materials, resulting in a material with enhanced properties
Smart material
A material whose physical properties change in response to an input or change in environment, such as electricity, pressure, temperature or light
Modern material
A material developed through the invention of new or improved processes, for example as a result of man-made materials or human intervention
Alloy
A metal made of two or more metals, or combining two or more elements, one of which must be a metal
Thermoplastic
A material that can be repeatedly reheated and re-shaped
Thermo setting polymer
A material which when heated undergoes a chemical change whereby the molecules form rigid cross links.
The setting polymers cannot be reheated and re-shaped even at very high temperatures
