About Microstrain (με)
Strain in units of 10⁻⁶ (parts per million; 1 με = 0.0001%). Microstrain is the universal working unit of foil-strain-gauge measurement per ASTM E251, semiconductor-strain-gauge instrumentation, fiber-Bragg-grating (FBG) optical strain sensors per ISO/IEC 81346, and Digital Image Correlation (DIC) strain mapping. Strain-gauge bridge-circuit outputs (Wheatstone full-bridge with shunt calibration) are typically calibrated and reported in με at the data-acquisition system (HBM QuantumX, NI cDAQ-9181 + 9237 modules, Vishay Micro-Measurements P3 strain indicator). Reference values: a typical highway bridge experiences 100-500 με under heavy-truck traffic per AASHTO LRFD load combinations; a fighter-jet wing-flex airframe-test can reach 2,000-5,000 με in flange spar caps during 9g pull-up; civil-structural health-monitoring (SHM) systems on dams + bridges + towers continuously log με data per ISIS Canada / fib Model Code 2010 guidance; aerospace fatigue-life prediction per FAA AC 25.571 uses microstrain spectra.
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.
