2. A material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling.
4. The intensity of distortion is known as strain.Two types:Plastic and elastic.
7. A solid material's ability to deform under tensile stress;this is often characterized by the material's ability to be stretched.
10. The strength or yield point of a material is the stress at which a material begins to deform plastically. Prior to this point, the material will deform elastically and will return to its original shape when the applied stress is removed.
13. The separation of an object or material into two, or more, pieces under the action of stress.
15. The ability of a material to absorb energy and plastically deform without fracturing.Requires a balance of strength and ductility.
17. The internal resistance, of a material to the distorting effects of an external force or load.
19. The measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied.
20. Conductance Measures how easily electricity flows along a certain path through an electrical element. It is the reciprocal of electrical resistance (measured in ohms).

1. The degree to which a material maintains its original dimensions when subjected to changes in temperature and humidity.
3. The weakening of a material caused by repeatedly applied loads. It is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading.
5. The twisting of an object due to an applied torque.
6. The electric charge that accumulates in certain solid materials in response to applied mechanical stress.
8. The reverse of tensile stress.Adjacent parts of the material tend to press against each other.
9. A measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 and 100%.
11. The tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses.Always increases with temperature.
12. Shear stress exists when two parts of a material tend to slide across each other.
14. Gradual destruction of a material by chemical reaction with its environment.
15. The stress in which the two sections of material tend to pull apart or elongate.
16. The volumetric mass density, of a substance is its mass per unit volume.
18. The expansion type that has atendency for matter to change in volume in response to a change in temperature.
