A discussion is given of three types of experimental techniques which make use of polymers for the verification of theoretical solutions to three‐dimensional linear fracture mechanics problems. The three techniques discussed are designated as the fatigue method, the photoelastic stress‐freezing method and the static fracture method. These techniques employ poly(methyl methacrylate) sheets which are cut into appropriate fracture mechanics specimen geometries or castable epoxies which may be cast into flat plates or other appropriate shapes for investigation. The suitability of these materials for linear fracture mechanics testing is discussed and the quality of results obtained is described.
