Numerical simulation of fatigue crack growth in welded pipes
(International Conference on Fracture, 2017)
Numerical simulation of fatigue crack growth has been performed by using the extended finite element method (xFEM) for modeling fatigue crack growth in a pipe made of API j55 steel by high-frequency welding. The obtained ...
Low-temperature corrosion damage and repair of boiler bottom panel tubes
(Institut za ispitivanje materijala, Beograd, 2017)
The method used for repairing of the bottom panel of hot water boiler of 30 MW power, manufactured by Remming (a part of the 'Valjevo' Heating Plant) is presented in this paper along with the reasons why damage has occurred. ...
Influence of Geometry on Pressure and Velocity Distribution in Packed-bed Methanol Steam Reforming Reactor
(Amer Inst Physics, Melville, 2017)
The main tasks of this research is to propose several changes in the packed bed micro methanol steam reformer geometry in order to ensure its performance. The reformer is an integral part of the existing indirect internal ...
The new experimental testing methodology for conveyor idler's fits control
(International Conference on Fracture, 2017)
The most common way to transfer tangential and axial loads in different types of assemblies is by interference fits. It is essential to determine interference fit parameters of pressed joints, which provides a proper ...
