Mechanical Properties Flashcards
List 7 mechanical properties
- Hardness
- Resilience
- Malleability
- Ductility
- Rigidity or Stiffness
- Corrosion Resistance
- Brittleness
Define Hardness
Resist deformation (denting, abrasion) when hit or scratched
Define resilience
resist shock and impact (deformation)
Define malleability
ability to be shaped without breaking
Define ductility
pulled into a wire or stretched without breaking
define stiffness/rigidity
ability to keep shape when subjected to various constraints
define corrosion resistance
resists smoke, salt, chemical products and oxidation (rusting)
define brittleness
Ability to shatter upon impact
List the 5 constraints
- Tension
- Compression
- Bending/deflection
- Torsion
- Shearing
Describe tension
Tension is a contact force and evidently, it stretches or pulls the object
describe compression
It pushes towards the object making it squeeze or even crushing it completely.
Describe bending/deflection
It’s a force that tends to cause a area to rotate or “bend” so that the straight area tends to assume a curved profile
describe torsion
twisting
describe shearing
A force that causes one part of a material to move opposite of the other, must be sharp and be able to slice
define the word constraint
a type of force or stress on an object
