Applying visual optical methods of non-destructive testing while diagnosing metal structures of mine hoisting plants

Interval Methods in Non-Destructive Testing of Material Structures

In many practical situations, e.g., in aerospace applications and in mammography, it is important to test the structural integrity of material structures. We show that interval methods can help.

Fuzzy Logic in Non Destructive Testing of Aerospace Structures

In nondestructive testing to locate the faults we send an ultrasonic signal and measure the resulting vibration at di erent points To describe and combine the uncertainty corresponding to di er ent measurements and fuzzy estimates we used fuzzy logic As a result we get reasonably simple computa tional models which lead to as good fault detection as the known more complicated models I Nondestruc...

Artificial neural networks for non destructive testing of concrete structures

In this paper, the determination of defects in concrete structures using an ultrasound technique is discussed. A diagnostic model for concrete pillars by means of Multi Layer Perceptron neural networks is developed to locate and classify the defects. Finite Elements numerical techniques have been used to model a concrete pillar of specified size (i.e., rectangular cross section and 2 meters in ...

Non-destructive Testing of Solid Brick Compression Strength in Structures

Solid burnt brick sized 290 × 140 × 65 mm or 303 × 145 × 70 mm respectively, represents one of most widespread brick building material, both structural and nonbearing ones, in Czech historical buildings. During their rebuilding and reconstruction, we frequently ask for brickwork material strength. Most exact method is to take test samples just from the construction and put them to trial neverth...
