Young modulus (EE) quantifies

Stiffness of a material

Young modulus measures resistance to

Deformation under stress

Young modulus formula (stress/strain form)

E=StressStrainE = \frac{\text{Stress}}{\text{Strain}}

Young modulus formula (expanded form)

E=F⋅LA⋅ΔLE = \frac{F \cdot L}{A \cdot \Delta L}

Stress-strain graph gradient (linear part) equals

Young modulus

High Young modulus means material is

Stiff (does not easily deform)

Low Young modulus means material is

Flexible

Example of stiff material (high EE)

Steel

Example of flexible material (low EE)

Rubber

SI unit of Young modulus

Pascal (Pa)
