Flashcards: Aerospace Structural Materials and Design — 10 cartões

Loads on aircraft — main types?

Ground and air loads.

Elasticity — definition?

Material returns to original shape after load removal.

Material failure modes — key?

Fracture, fatigue, corrosion.

Ductility — role?

Allows plastic deformation before fracture, warning of failure.

Elasticity — definition?

Material's ability to return to original shape after deformation.

Strength — maximum?

Maximum stress a material can withstand without failure.

Toughness — capacity?

Absorbing energy without fracturing; balance of strength and ductility.

Brittleness — characteristic?

Fractures with little plastic deformation, sudden failure.

Fatigue — damage?

Weakening due to cyclic loading, leading to failure.

Material selection factors?

Strength-to-weight, stiffness, toughness, corrosion resistance, fatigue life, cost.
