Key values (for reference)
ⓘ Assumptions
Centred tensile load, constant cross-section and homogeneous linear elastic material. Stress concentrations, bending and local joint effects excluded. Young’s modulus is converted from GPa to MPa.
Equations & calculation model
ε = σ / E
δ = FL / (AE)
Idealised calculations for preliminary design. Check geometry, loading and boundary conditions against your application.
What it is used for
Estimating direct tensile strain, stress, and extension of a uniform member.
Standards & references
OpenStax University Physics: stress, strain and elastic modulus. The model assumes uniform axial stress and linear elasticity. It excludes joints, bending and local stress concentrations; it does not determine an allowable design load.
