... basic building block of the laminate. In order to perform engineering analysis, the heterogeneous lamina consisting of a fiber phase and a matrix phase is treated as a homogeneous, orthotropic material. In addition, laminate modeling assumes that plies are in a state of plane stress...

... m/s (4900 ft/s) in water. Transverse waves (shear waves) also are used extensively in ultrasonic inspection of metals. Transverse waves are visualized readily in terms of vibrations of a rope that is shaken rhythmically, in which each particle vibrates up and down in a plane perpendicular to the...

... understanding of the limitations on ultrasonic NDT capabilities for sizing. The relationship between defect assessment and NDT can occur in two ways. The first, in many cases, is for NDT to find a defect that is then subsequently assessed to establish the fitness for purpose of the component. Second, a...

..., angle, and distance. Considering the attenuation due to scatter and absorption, the sound pressure of a plane wave in the far field can be represented by: (Eq 5) p = p 0 e − α d where p is the end pressure, p 0 is the initial pressure, α is the attenuation coefficient, and d...

... of a plate, strip, or wire in which the thickness is on the order of a few wavelengths, it may be beneficial to use Lamb waves ( Ref 11 ). Lamb waves (or plate waves) are elastic waves that propagate in plates of finite thickness as guided waves and are associated with particle motion in a plane...

... various combinations of loading Modes I, II, and III, as well as the constant change in orientation of the local plane of fracture as the crack propagates, result in asymmetrical straining of the mating fracture surfaces. Figure 8 shows the effect of such asymmetry on dimple size. The surface (B) that...

Laminated glass also gives the maximum possible protection against ultraviolet (UV)-induced fading of furnishings and organic-based materials without any major reduction of visible light transmission. Further reduction of UV transmission requires tints and coatings with...
