Materials Flashcards
What is Compression?
Forces that tend to crush.
What is Tension?
Forces that tend to stretch.
What is Torsion?
Forces that tend to twist.
What is Deflection?
Forces that tend to bend.
What is Shearing?
Forces that to cut.
What are Constraints?
Forces that deform parts.
What are Mechanical Properties?
Physical properties that a material exhibits upon the application of forces.
What is Hardness?
Ability to resist indentation or abrasion.
What is Elasticity?
Ability to return to it’s original form after under going a constraint.
What is Resillience?
Ability to resist shocks without breaking.
What is Ductility?
Ability to be stretched without breaking.
What is Malleability?
Ability to be flattened or bent without breaking.
What is Stiffness?
Ability to maintain their shape when subjected to various constraints.
What is a Elastic Deformation?
A temporary change in the shape or dimensions of the material, which returns to it’s original form once the constraint is removed.
What is a Plastic Deformation?
A permanent change in the shape or dimensions, which stays deformed after the constraint is removed.
What is a Fracture Deformation?
The constraint is so intense the material breaks.
What is Resistance to Corrosion?
Ability to resist the effects of rust formatting.
What is Electrical Conductivity?
Ability to carry an electrical current.
What is Thermal Conductivity?
Ability to transmit heat.
What are the two types of plastics?
Thermoplastic and Thermosetting.
