Engineering Materials
4 original lesson summaries in this topic collection.
Topic overview
- Normal stress σ = F/A acts perpendicular to an area; shear stress τ = F/A acts parallel.
- Strain ε = ΔL/L; in the elastic range E = σ/ε.
- Key curve points: proportional limit, yield or 0.2% proof stress, UTS, necking and fracture.
- FoS = failure stress ÷ working stress, chosen for uncertainty and consequence.
