Material Properties

Yield Strength (

F_y

)36 ksi

Tensile Strength (

F_u

)58 ksi

Elastic Modulus (

E

)29,000 ksi

Regions of the Curve:

Elastic: Linear region up to $F_y$ . Material returns to original shape.
Plastic Plateau: Deformation with no increase in stress.
Strain Hardening: Stress increases up to $F_u$ .
Necking: Cross-section decreases, stress drops until fracture.
