σ
210 MPa
ΔL (L₀)
1 mm

E in GPa; ε is dimensionless strain.

How it works

Apply Hooke's law to relate stress, strain, and Young's modulus in the elastic region.

Who it's for: Materials science and structural students analyzing elastic deformation.

σ = E·ε in the linear elastic range.

E in GPa; ε is dimensionless strain.

ΔL = ε·L₀ for a member of original length L₀.

How to use

  1. Enter Young's modulus E, strain ε (or stress σ to solve the other).
  2. Read stress, strain, and length change ΔL.
