Institutional teaching source, Strength and Stiffness Characteristics, Secant Modulus definition and pointA diagram. Defines the origin-to-point slope, dependence on the selected point, and notation Es. No individual author or publication date is inferred. The article's polynomial, integral identity and tensile numbers are original derivations.

Institutional Materials and Mechanics glossary, Elastic Modulus entry. The final two lines define tangent modulus as the local derivative of stress with respect to strain for nonlinear elastic response; preceding text distinguishes the initial linear Young modulus. No individual author or publication date is inferred from the page.

MIT Department of Materials Science and Engineering module dated21November2000. Normal Stresses, pp.2–4, equations3–6: strain, second moment of area, linear elasticity and moment-curvature relation. Only these beam mechanics relations underpin the independent equal-material bundle calculation.

Primary course reading, Aerospace Mechanics of Materials, Axial Loaded Members. Force-displacement slope; axial relation delta=PL/(EA), structural stiffness EA/L, and distinction between geometry and material contributions. No named individual byline is inferred from institutional authorship.

Primary manufacturer technical note, pp1–3. Page1 explains deformation of the frame, load cell, grips and specimen; pp2–3 describe a stiff dummy specimen in the same load string and subtraction of its displacement at matching forces. Used for measurement-path context and the assumptions of a compliance correction, not adopted software recommendations or accuracy specifications.

Primary manufacturer documentation. Passage explaining when an extensometer is needed: crosshead displacement includes machine compliance, grip seating and load-train deflection. Used only to distinguish specimen and machine displacement, with no adopted performance claim or recommendation.

Primary University of Illinois facility description, Load Frames: Instron4483 ball-screw crosshead, crosshead-mounted load cell, optional specimen extensometer and position encoder; signals converted to engineering units and stored. Used for apparatus and measured channels, not a product recommendation or accuracy specification.

Primary NASA technical-report metadata and author abstract: twelve light-aircraft crash pulses; two vertical drop tests of an energy-absorbing prototype at 12.8 m/s and 36 G peak deceleration. The SAE publisher names Emilio Alfaro-Bou and gives DOI 10.4271/810611. NASA labels its record 1 April 1981, while SAE labels publication 1 February 1981; the publication year 1981 agrees.
