Elastic Modulus & Energy

Apply Hooke's law to compute elastic modulus E, shear modulus G and strain energy U=W²l/(2AE).

Inputs

Formula

E = σ/ε; G = τ/γ; U = W²l/(2AE)

How to use

  1. Fill in Normal stress σ, Axial strain ε, Shear stress τ, Shear strain γ, Load W, Length l in the Inputs section (watch the unit on each field).
  2. Click Calculate; the tool evaluates the formula shown above.
  3. Read Elastic mod. E, Shear mod. G, Strain energy U in the results area.
Formula notesYoung's modulus E = σ/ε; shear G = E/(2(1+ν)); bulk K = E/(3(1−2ν)).
