Elastic modulus is a general term for the ratio of stress to strain in materials, while Young's modulus specifically measures this ratio for linear elastic deformation under tension or compression.
The Youngs modulus does not depend on the geometry of the material. With the change in shape, length, themoment of inertia, weight, etc. the value of the modulus of elasticity does not change. Which is more elastic: Rubber or Steel? Young’s modulus signifies the elasticity of a material...
“stress-strain curve,” and it shows how strain changes with applied bending stress. The slope of this curve in the region where elastic strain occurs defines the flexural modulus of the material. The units of measure are, in most cases, pounds per square inch (psi) or Newtons per square...
