Push-out and pull-out tests are used for destructive evaluation of implant-bone interface strength. Because nondestructive mechanical tests would allow maintenance of an intact interface for subsequent morphological study, we developed such a test to determine the shear modulus of the interface by measuring the shear deformation of a thin layer adjacent to the implant. A polyurethane foam model...

This study was conducted to determine the relationship between nondestructive and destructive tests in concrete cubes using different ratios of normal stone recycled brick as coarse aggregates. Variations grade concrete, density, age were considered make model prediction more efficient places where use aggregates is common. Normal grades M20, M25, M30 having density variation by replacing with ...

The detection, isolation, and characterization of flaws in components represent a critical need in manufacturing and quality control. Nondestructive testing (NDT) provides an effective way of inspecting materials for ensuring the quality and integrity of products and systems. Consequently, nondestructive inspection finds extensive application in several industries such as steel, nuclear and ele...

Quality control in the orthopedical diagnostics according to DIN EN ISO 9000 ff requires methods of nondestructive process control, which do not harm the patient neither by radiation nor by invasive examinations. To gain an improvement of health economy quality controlled and nondestructive measurements have to be introduced in the diagnostics and the therapy of human joints and bones. There is...

The three-dimensional(3-d) reconstruction and visualization of serials of industrial computed tomography(ICT) images is an important research aspect for large objects nondestructive detection. In the course of 3-d reconstructions of the continuous equidistant ICT images, the contour lines of every tomogram are picked out and joint by triangles in serialized order. After the stereo images of the...

Nondestructive testing (NDT) is an advanced and commonly used technique in tunnel engineering quality inspection. To achieve good application of nondestructive technology, its main inspection strategy analyzed, including the significance applying technology inspection, applied test analysis, analysis strategy. The analyses this paper are done hopes providing scientific reference for utilization...

Composite materials are often more practical in use for different military applications. These materials provide interesting results especially through their good strength properties, corrosion resistance and low specific weight. These materials have various structures. Any defect of these materials usually has a more complicated and other form than in metals and that is why methods and diagnos...
