In previous work, a modified double torsion test was developed to measure the fracture toughness of polymeric ophthalmic lenses with parallel surfaces. The method used production lenses so that the toughness of the manufactured articles could be measured directly. This method has now been extended t

The stress-intensity factor calibration of the double-torsion specimen is discussed. It is argued that accurate analysis requires an accurate description of the shape of the steady crack profile which evolves in a particular test. The line-spring model, which readily accommodates variable depth crac
