About Percent Strain (%)
Strain expressed as percentage of original length (ε × 100%) — the default reporting unit on every tensile-test stress-strain curve in materials-science publication, materials-property databases (MatWeb, NIST MMP, Granta Selector, MMPDS), and ASM Handbook material data sheets. Used universally for: yield strain (aluminum 6061-T6 yields at ~0.5% strain, mild structural steel yields at 0.2% strain — the basis of the 0.2% offset yield-strength definition per ASTM E8/E8M), elongation at break per ASTM E8 (the percent value shown on every metal's data card — 6061-T6 has 12% elongation at break, mild steel 25-30%, brass alloys 30-65%, polyethylene 100-700%, EPDM rubber 300-600%), and fracture-toughness J-integral analysis. Steel-reinforced concrete strain limits per ACI 318: tension steel must reach ε ≥ 0.005 (0.5%) for tension-controlled design.
About Inch per Inch (in/in)
Strain expressed as inches of deformation per inch of original length — numerically identical to unitless strain ε and to mm/mm ratio (since strain is fundamentally dimensionless), but the in/in notation is the US engineering convention on US-units material data sheets. Used universally on: US material data sheets per MMPDS (Metallic Materials Properties Development and Standardization) and ASM Handbook (alloys like 6061-T6 aluminum, 4140 steel, 4340 steel, Inconel 718, Ti-6Al-4V all list elongation at break in in/in alongside percent on certificates of conformance per ASTM E8/E8M tensile-test method), US-edition machine-design textbooks (Shigley, Norton, Budynas-Nisbett), US aerospace stress reports per SwRI / NASA / Lockheed Martin internal standards, and US structural-engineering bolt-elongation-method preloading documentation per RCSC bolt-preload specifications. Convert in/in to percent strain by multiplying by 100; to microstrain by multiplying by 10⁶.
