The surface conditions, therefore, greatly influence the economics of testing.作者: 偽造 時(shí)間: 2025-3-22 19:55 作者: cultivated 時(shí)間: 2025-3-22 21:47 作者: 領(lǐng)巾 時(shí)間: 2025-3-23 05:13
Sound Emission Analysis (SEA)This method of non-destructive testing will be treated only briefly because it has little similarity to traditional ultrasonic testing, and also because it has not achieved widespread applications in practice. Testing specifications for pressure vessels have, however, already been produced.作者: incontinence 時(shí)間: 2025-3-23 07:23 作者: hair-bulb 時(shí)間: 2025-3-23 12:44

Ultrasonic Waves in Free Space of an elastic body can be visualised as shown in Fig. 1.2, but three-dimensionally. Provided such a body is not stressed by compression or tension beyond its elastic limit, it behaves like this spring model. In it, the particles can perform elastic oscillations. How then does a wave arise from an o作者: stressors 時(shí)間: 2025-3-23 23:46

Ultrasonic Waves in Free Spaceal wave is composed of oscillations of discrete particles of material. The motion carried out by a small mass attached to a spring as shown in Fig. 1.1 if pulled down once and released, is called an oscillation. Left to itself, the mass oscillates about the equilibrium position.

Piezo-electric Methods of Generation and Reception of Ultrasonic Waves are referred to in materials testing as a ., or ., and where applicable as a transmitting probe or a receiving probe.

Other Methods for Transmitting and Receiving Ultrasoundof the workpiece concerned. Compared with the piezo-electric oscillator, which is coupled to the workpiece, the surface of the work piece forms in the case of these “direct” methods a part of the acoustic transducer. The direct or dry methods thus require no coupling medium, and so avoid some of the difficulties analysed in the paragraph below.作者: 誘惑 時(shí)間: 2025-3-28 21:19 作者: orthopedist 時(shí)間: 2025-3-29 02:45 作者: GEN 時(shí)間: 2025-3-29 03:49
