Young''s modulus - Wikipedia

2019-4-19 · Young''s modulus or Young modulus is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation. Young''s modulus is named after the 19th-century British

What Is Young''s Modulus? Definition and Equation

Young''s modulus (E or Y) is a measure of a solid''s stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed.
