Numerical simulation of fatigue crack growth in friction stir welded T joint made of Al 2024 T351 alloy
(Elsevier Science Bv, Amsterdam, 2016)
The Extended Finite Element Method (xFEM) has been applied to simulate fatigue crack growth in an AA2024-T351 T welded joint, 5 mm thick, made by friction stir welding. The ABAQUS and Morfeo software has been used. Tensile ...
Local deformation fields and marginal integrity of sculptable bulk-fill, low-shrinkage and conventional composites
(Elsevier Sci Ltd, Oxford, 2016)
Objective. To compare strain and displacement of sculptable bulk-fill, low-shrinkage and conventional composites as well as dye penetration along the dentin-restoration interface. Methods. Modified Class II cavities (N= ...
Automated identification of land cover type using multispectral satellite images
(Elsevier Science Sa, Lausanne, 2016)
Detection of specific terrain features and vegetation, referenced as a landscape classification, is an important component in the management and planning of natural resources. The different land types, man-made materials ...
Abrasive wear behaviour of ADI material with various retained austenite content
(Taylor & Francis Ltd, Abingdon, 2016)
In this paper, the wear rate of ferritic and pearlitic ductile iron, as well as three types of austempered ductile iron (ADI materials), austempered at 300, 350 and 400 degrees C is investigated. Two wear parameters were ...
Identification of modular firefighting superstructures' dynamic behaviour
(Vibromechanika, 2016)
Specific functional requirements for firefighting vehicles have resulted in stricter exploitation regimes and frequent off-road use. Current practice appoints the problem of the strength of a superstructure's modules, which ...
