Properties of material Flashcards
1
Q
what does a stronger attraction between atoms do to the elastic modulus
A
increases elastic modulus
2
Q
what is strain
A
deformation when body is subjected to force
3
Q
what is yield strength
A
stress at which material deformed plastically with defined amount of permanent strain
4
Q
what is ultimate tensile strength
A
max stress material can take before failure
5
Q
What is fracture strength
A
max stress material can take before failure, depending on shape
6
Q
What is fracture toughness
A
total energy absorbed by structure before frature, does not depend on shape ( is the total area under the curve)
7
Q
brittle material have ___ tensile strength and ___ compressive strength
A
low…. much higher
