What is the Young’s Modulus or Modulus of Elasticity?
The Young’s Modulus (or Modulus of Elasticity) describes the limit for small strains of the rate of change of stress with strain a material is able to support. Many natural stones have a Modulus of Elasticity of around 50 Gpa (which translates to 50.000 N mm-2, depending on the stone), with pure Quartz reaching a Young’s Modulus of 71.7 GPa.
