About the Young's Modulus Calculator
Young's modulus (elastic modulus) measures a material's stiffness. It is the ratio of stress to strain in the linear elastic region. A higher modulus means a stiffer material. Steel has a modulus of about 200 GPa, aluminum about 69 GPa, and rubber about 0.01-0.1 GPa. Young's modulus is fundamental to structural engineering because it determines how much a structure will deflect under load.
Frequently Asked Questions
What is a typical Young's modulus for steel?
Structural steel has a Young's modulus of approximately 200 GPa (200 x 10^9 Pa).
Does temperature affect Young's modulus?
Yes. Young's modulus generally decreases as temperature increases because atomic bonds become weaker at higher temperatures.
What is the difference between Young's modulus and shear modulus?
Young's modulus measures resistance to axial deformation (tension/compression). Shear modulus measures resistance to shear deformation. They are related through Poisson's ratio.
