WebJan 1, 1978 · Table 1 lists the stress-intensity factors as calculated from the coating and the specimen isochromatics along with crack position and velocity for one of the tests. For the three tests, the stress intensity factor calculated from the coating isochromatics was consistently about 3% higher in value.
WebA simple formula is derived to describe the effect of radial pressure on the birefringence in a coated birefringent optical fiber. Both plastic and metal coating materials are studied. Theoretical analysis shows that the pressure-induced birefringence in the fiber is determined mainly by the elastic properties of the fiber glasses and is rather insensitive to the … WebThe method of birefringent coatings for the determination of elastic and plastic surface strains of opaque bodies like metals assumes perfect elasticity of the coating material. …
