Definitions of Materials Flashcards
1
Q
Elastic
A
Returns to unstretched form when stresses are removed
2
Q
Plastic
A
When stretched will remain in new shape (Plastic deformation)
3
Q
Opposite of elastic
A
Plastic
4
Q
Opposite of plastic
A
Elastic
5
Q
Brittle
A
Undergoes little to no plastic deformation before fracture
Fails by cracking
6
Q
Tough
A
Absorbs a lot of energy before fracture (deforms plastically)
7
Q
Opposite of brittle
A
Tough
8
Q
Opposite of tough
A
Brittle
9
Q
Strong
A
Takes high stresses before breaking
10
Q
Opposite of strong
A
Weak
11
Q
Flexible
A
Low stress needed to change shape
12
Q
Stiff
A
Small extension per unit force (high young mod)
13

Hard
A
Does not dent or scratch on impact
