A computer program for calculating principal stresses in photoelasticity [electronic resource] / M. Gyenge, Fuels and Mining Practice Division. Ottawa : Queen's Printer, 1967. iii, 12 p. Technical bulletin ; TB 88 Cover title. "March 1967." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 10). “Slope stability research is being conducted to increase our knowledge of the mechanics of rock slopes -- a subject of great importance in open pit mining. Stress analysis problems, where the major active force is gravity, give rise to several special requirements when photoelastic models are being used. The use of a computer program for the separation and computation of the principal stresses means that the stress distribution within the entire model can be obtained quickly. It saves enormous amounts of time in comparison with manual computation and therefore the efficiency of the model testing procedure is greatly increased"--Abstract, p. i.
