Properties of Engineering Materials Flashcards
Description of physical behavior: Density Specific Gravity Porosity Water absorption
Physical Properties
2 Types of Density
Mass per unit volume:
bulk density
dry density
The ratio of the density of the material to the density of water.
Specific gravity
The ratio of the volume of spaces to the overall volume
Porosity
Ratio of volume of voids to volume of solid materials
Void
Ability of material to absorb and retain water
Water absorption
Amount of water in the soil
Total moisture content
Relates to its behavior in a chemical reaction:
Corrosion
Alloying
Compound formation
Chemical Properties
Properties in terms of strength, tension, compression, shear, bending, torsion
Mechanical Properties
How materials do not suffer from permanent change
Elasticity
How materials suffer from a permanent change of form
Plasticity
Materials withstand but with great deformation, high-stress w/o fracture
Toughness
Can be practically compressed
Malleability
Material that resists abrasion or resistant pressure
Hardness
The ability of a material to resist failure under actions of stress
Strength
