Failure resistance of drilling rig casing pipes with an axial crack
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
Exploring innovative solutions for aged concrete utilization: treatment of liquid radioactive waste
(Springer, New York, 2018)
In this study, the applicability of waste concrete as a sorbent material for the liquid radioactive waste management was considered. The sample was properly characterized in terms of mineralogical and surface composition, ...
The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
Experimental Investigation of the Efficiency of Heat Pump Drying System with Full Air Recirculation
(Wiley, Hoboken, 2017)
The paper presents results of an experimental investigation of convective drying of apples var. Idared, potatoes var. Desiree and bananas var. Grand Nein, in full recirculation laboratory-scale dryer. The experiments were ...
Simplified method for generating slope seismic deformation hazard curve
(Elsevier Ltd, 2015)
A simplified method for generating slope deformation hazard curve that takes into account the variations of input parameters is presented in this paper. The main assumption in the new approach is that the occurrence of ...
Isogeometric bending analysis of composite plates based on a higher-order shear deformation theory
(Korean Soc Mechanical Engineers, Seoul, 2014)
This research paper presents an isogeometric plate finite element formulation for analysis of thick composite plates. Isogeometric finite element method which is based on non-uniform rational B-splines (NURBS) basis ...
Numerical simulation of fatigue crack propagation in friction stir welded joint made of Al 2024-T351 alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded T joints has been simulated numerically. Crack propagation in stiffened part of the structure between two ...
Water deoxygenation using hollow fiber membrane module with nitrogen as inert gas
(Taylor & Francis Inc, Philadelphia, 2015)
A pilot plant scale fiber membrane system was developed for the removal of dissolved oxygen from water via nitrogen vacuum. Feed water was introduced to the shell side; a nitrogen gas was applied to the lumen side, as an ...
