The Young''s Modulus of Silicon
Anisotropic Elasticity Hooke''s law describes the linear, isotropic relationship between stress (σ) and strain (ε) using compliance (S) and stiffness (C):σ=Cε , or ε=Sσ . The mechanical stiffness of materials under uniaxial loading is called the Young''s modulus, and is typically represented by the syol E in engineering texts, so Hooke''s law is often written as σ=Eε .
