Work out young modulus instantly with clear inputs, formula shown and shareable results.
Young's modulus is the slope of the elastic part of the stress-strain curve, stress divided by strain. 150 MPa producing 714 microstrain gives 210 GPa, the standard figure for steel. Because modulus is a material property, it is unaffected by the specimen's size - unlike stiffness, which also depends on geometry.
Young's modulus
E = stress / strain
Typical values
steel 200-210 GPa, aluminium 69 GPa, concrete 30 GPa
Not necessarily. Modulus measures resistance to elastic deformation; strength is the stress at which it fails. Glass is stiff but brittle.
Barely. Modulus depends on atomic bonding, so hardening changes strength dramatically while leaving stiffness almost untouched.
