Guest editorial: Advanced design and fatigue assessment of structural components
(Wiley, Hoboken, 2019)
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
The synergistic action and interplay of hydrogen embrittlement mechanisms in steels and iron: Localized plasticity and decohesion
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Component failures due to the hydrogen embrittlement (HE) were observed in different industrial systems, including high-pressure hydrogen storage tanks, aircraft components, high-strength alloy components, and high-strength ...
Austempering Kinetics of Cu-Ni Alloyed Austempered Ductile Iron
(Korean Inst Metals Materials, Seoul, 2014)
The aim of the paper was to investigate the effect of austempering parameters (time and temperature) on the microstructure and mechanical properties of ADI alloyed with 1.5% Cu and 1.6% Ni (in wt.%) in order to establish ...
Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module - Part 1: Presentation of test section and 3D CFD model
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with cooling of the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module (HCPB TBM) for ITER. The first wall cooling is an important investigation issue due to an extreme asymmetry of heat loads: ...
Experimental studies on active vibration control of smart plate using a modified PID controller with optimal orientation of piezoelectric actuator
(Sage Publications Ltd, London, 2016)
This paper presents a design, development and experimental verification of an active vibration control system of aluminum plate. The active structure consists of an aluminum rectangular plate as the host structure, strain ...
Picosecond Laser Shock Peening of Nimonic 263 at 1064 nm and 532 nm Wavelength
(MDPI, Basel, 2016)
The paper presents a study on the surface modifications of nickel based superalloy Nimonic 263 induced by laser shock peening (LSP) process. The process was performed by Nd3+:Yttrium Aluminium Garnet (YAG) picosecond laser ...
Stringer effect on fatigue crack propagation in A2024-T351 aluminum alloy welded joint
(Elsevier Sci Ltd, Oxford, 2017)
This paper describes fatigue crack growth in a friction stir welded T joints made of aluminum alloy A2024-T351 under three point bending loads. For this purpose, three dimensional homogeneous isotropic model is used to ...
Experimental investigations of flow distribution in coolant system of Helium-Cooled-Pebble-Bed Test Blanket Module
(Elsevier Science Sa, Lausanne, 2016)
This paper deals with investigations of flow distribution in the coolant system of the Helium-Cooled Pebble -Bed Test Blanket Module (HCPB TBM) for ITER. The investigations have been performed by manufacturing and testing ...
Ductile fracture of pipe-ring notched bend specimens - Micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Integrity of pipes is typically assessed by testing fracture mechanics specimens, such as compact tensile (CT) or single-edge notched bending (SENB). However, for some pipe dimensions it is not easy or possible to fabricate ...
