G = E / [2(1 + nu)]
K = E / [3(1 - 2nu)]
Youngs modulus values are typical reference values. Use grade-specific datasheets for final deflection or stress analysis.
Reference
Youngs modulus measures resistance to elastic deformation under normal stress.
Beam, shaft, and plate deflection calculations depend strongly on elastic modulus.
Elastic modulus is a core material input for linear finite element models.
Higher modulus materials are stiffer for the same geometry.
FAQ
A common reference value for carbon steel is about 200 GPa.
A common reference value for aluminum is about 69 GPa.
Youngs modulus is a material stiffness property; actual part stiffness also depends on geometry.
