Term
Extensive Property
Definition
Directly proportional to the system size or the amount of material in the system.
Term
Intensive Property
Definition
Does not depend on the system size or the amount of material in the system
Term
Ductile Structural Failure
Definition
preferred mode:
Yielding =>
warning of problems
load transfer to other components
can carry failure load
Term
Brittle Structural Failure
Definition
bad mode:
Buckling
Fracture
=> can lead to sudden collapse
=> little load carrying capacity after failure
Term

Definition
concrete, glass, cement
Term
Polymer
Definition
plastic, rubber
Term
Metal
Definition
aluminum, steel
Term

Term
Machinability
Definition
The difficulty of removing a material by the cutting action of a hard tool to produce complex shapes.
Term
Formability
Definition
The difficulty by which a material can be forced into a new shape in the solid state by use of pressure.
Term
Castability
Definition
The difficulty by which a material can be melted or poured into a mold.
Term
Moldability
Definition
The difficulty by which a polymer can be forced into a desired shape using pressure.
Term
