Experimental Strain Analysis by David Roylance

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.
