Mass
The amount of matter contained in a space
Volume
The amount of 3D space a solid, gas, or liquid occupies
Density
Relationship between mass and unit of volume
Electrical Resistivity
A material’s ability to conduct or resist electricity
Thermal Conductivity
Measures how fast heat moves through a material
Thermal Expansion
The degree to which a material increases its dimensions when its heated
Hardness
The resistance of a material to scratching or penetration
Mechanical Properties
Properties of materials that are usually measured through some form of destructive testing
Physical Properties
Properties of materials that can be measured through non-destructive testing
Tensile Strength
The ability of a material to resist pulling forces
Compressive Strength
The ability of a material to resist pushing forces
Stiffness
The ability to resist bending by a force so that an object maintains its shape when a force is applied to it
Toughness
The ability to deform, but resist cracking/fracturing under impact.
Ductility
The ability to be drawn or extruded into a wire-like form
Elasticity
The ability of a material to bend and then return to its original shape
Plasticity
The ability of a material to be formed into a new shape
Young’s Modulus
Measure of the stiffness of an elastic material using the ratio of stress to strain of a material as force is applied along its length.
Stress
The tensile force applied to a given area
Strain
The percentage of change in length when a force is applied to the initial length
Region of Elasticity
Space on a stress-strain graph where the material would return to its original shape if the material was stretched and then released.
Yield Point
The point on a stress-strain graph where the material will no longer return to its original shape
Ultimate Tensile Strength (UTS)
The point at which the material can maintain a maximum load.
Necking
A mode of tensile deformation where large amounts of strain localize disproportionately in a small region of the material
Failure Point
The point on a stress-strain graph at which the material actually breaks
Aesthetic Properties
Properties that are related to beauty and pleasure derived from a material
Texture
How a material feels or looks
Appearance
The color or pattern of a material
Smart Materials
Reactive materials that change their properties when exposed to stimuli such as electrical charges, moisture, or temperature
Piezoelectricity
The ability to release an electric charge when deformed
Shape Memory Alloys
Materials that allow their bodies to return to their original shape after deforming
Photochromacity
The ability to change color when exposed to light
Magneto-rheostatic fluids
Fluids that undergo a change in their viscosity when a magnetic force is applied
Electro-rheostatic fluids
Fluids that undergo a change in their viscosity when an electrical force is applied
Thermoelectricity
Two different conductors that, when joined together, generate electricity when heat is applied.
