MIT Department of Materials Science and Engineering module dated 30 November 2000. Introduction and Multiple integration, Example 1, pp. 1–3: simply supported central-load response and flexural-modulus inference; equation 7 gives the midspan deflection. The article uses positive downward displacement, opposite the signed displacement convention in the module.

Primary MIT teaching document: ocw.mit.edu/courses/3-11-mechanics-of-materials-fall-1999/9cb0de418008f7516c08a7df6b91bb5c_MIT3_11F99_expt.pdf . David Roylance, 23 February 2001, as printed on the first page. Photoelasticity subsection, printed pp. 5–8: stress-dependent birefringence; p. 6 gives the stress-optical law and its wavelength-dependent coefficient; pp. 7–8 describe crossed-polarizer analysis and fringe interpretation. The OCW file listing calls the item Experimental Solutions; the document itself is headed Experimental Strain Analysis.

MIT teaching module dated 14 June 2001. By David Roylance.

Verified primary passage: printed pp. 8–11, equation (5) and specimen-geometry discussion: critical stress intensity, crack size and small-plastic-zone validity. The numerical example in the wiki is independently calculated.

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.
