Hooke's Law

Created by Robert Hooke
Fundamental linear elastic relation between uniaxial Stress and Strain

Where:

• $E$ is the "modulus of elasticity" also known as "Elastic Modulus" or "Young's Modulus"
• $\sigma$ is Stress
• $ϵ$ is Strain

Hooke's Law in Shear

Where:

• $\tau$ is the Shear Stress
• $G$ is the Shear Modulus
• $\gamma$ is the Shear Strain
