Towards a unified and practical industrial model for prediction of hydrogen embrittlement and damage in steels
(Elsevier Science Bv, Amsterdam, 2016)
Bearing in mind the multiple effects of hydrogen in steels, the specific mechanism of hydrogen embrittlement (HE) is active, depending on the experimental conditions and numerous factors which can be grouped as environmental, ...
Analysis of the effect of implant distance from the surrounding structure, in the PMMA block model
(Elsevier Science Bv, Amsterdam, 2016)
Strain analysis in the vicinity of the dental implants were the subject of many research papers. In this study, new experimental method was employed for strain determination in the surrounding area of the axially loaded ...
Oxidation behavior during prolonged service of boiler tubes made of 2.25Cr1Mo and 12Cr1Mo0.3V heat resistance steels
(Elsevier Science Bv, Amsterdam, 2016)
During service of thermal power plant (TPP) units, different components are exposed to high temperature due to technological cycle of TPP unit. Service lifetimes of these components, especially boiler heating surfaces, may ...
Elastic-plastic behaviour of welded joints during loading and unloading of pressure vessels
(Elsevier Science Bv, Amsterdam, 2016)
In this paper elastic-plastic behaviour of welded joints during loading and unloading of pressure vessel has been analysed. Two stage pressuring process has been applied in previous experimental investigation and simulated ...
Numerical prediction of ductile fracture resistance of welded joint zones
(Elsevier Science Bv, Amsterdam, 2016)
This study deals with the numerical prediction of ductile fracture initiation and development in welded joints of a high strength low alloyed steel. Having in mind the material heterogeneity in the joint zone, a combined ...
Risk Based Approach to Integrity Assessment of a Large Spherical Pressure Vessel
(Elsevier Science Bv, Amsterdam, 2016)
The risk based approach has been applied, in its simplest form, i.e. by using the risk matrix to illustrate how the water proof test can shift risk from high to very high level in the case of large spherical pressure vessel ...
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 ...
