    Non-destructive evaluation of a component material by an acoustic impact method was fundamentally investigated for the simplified square samples with artificial defects. Frequency spectrum, which was obtained by a fast Fourier transform of an acoustic wave form, was discussed for the evaluation of the defects on the specimen. Ultrasonic Inspection is a very useful and versatile NDT method. Some of the advantages of ultrasonic inspection that are often cited include: It is sensitive to both surface and subsurface discontinuities. The depth of penetration for flaw detection or measurement is .

A method of non-destructive testing, the method comprising: locating an ultrasonic transducer with respect to a component having a visually-inaccessible structure to collect B-scan data from at least one B-scan of the component and to collect C-scan data from at least one C-scan of the component; filtering the B-scan data and the C-scan data Author: Ehsan Dehghan Niri, Curtis Wayne Rose, Amir Riahi, Eric Michael Shain. This paper presents an assessment of the condition of wood coming from a wharf timber sheet wall after 70 years of service in a (sea) water environment. Samples taken from the structure’s different zones, i.e., the zone impacted by waves and characterised by variable water-air conditions, the zone immersed in water and the zone embedded in the ground, were Cited by: 2.

    The use of impact-echo acoustic method to test cement-based mortar composites modified with rubber aggregates and EVA polymer binder and degraded at high temperatures was studied. The specimens were prepared by using a type CEM I Portland cement and siliceous sand, as well as by substituting 25% of sand with shredded automobile tires and by adding EVA polymer binder Cited by: 2. Liquid penetrant inspection technique is a widely applied and low-cost inspection method used to locate the surface breaking defect in all non-porous material including metals, plastics, ceramics and composites. Penetrant may be applied to all non-ferrous materials but magnetic particle inspection is preferred for inspection of ferrous componentsCited by: 2.

A review provided about non-destructive testing (NDT) methods for the evaluation of composites. The review considers the capabilities of most common methods in composite NDT applications such as Visual Testing (VT or VI), Ultrasonic Testing (UT), Thermography, Radiographic Testing (RT), Electromagnetic Testing (ET), Acoustic Emission (AE), and Shearography Testing with Cited by:   Non Destructive Testing Methods The number of NDT methods that can be used to inspect components and make measurements is large and continues to grow.

Researchers continue to find new ways of applying physics and other scientific disciplines to develop better NDT methods. However, there are six NDT methods that are used most often. NDT of metallic materials is a very important application, NDT is being used increasingly for the inspection of concrete structures.

Training Course Series Nos. 3 and 10 cover the inspection of concrete using the relevant NDT method; however, coverage is brief and does not present the whole range of NDT methods used for the NDT of concrete.
