Calculate the elastic modulus of a material based on stress and strain.
Must be ≥ 0
Must be > 0
Must be > 0
Positive (stretch) or negative (compress)
Young's modulus (E) is a measure of the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in the linear elastic region.
A high Young's modulus means the material is stiff and resists deformation (e.g., Steel: ~200 GPa). A low Young's modulus means the material is flexible (e.g., Rubber: ~0.01 GPa).
Where σ is stress, ε is strain, F is force, A is area, ΔL is change in length, and L₀ is the original length.
