Probability distribution on cleavage fracture in function of Jc for reactor ferritic steel in transition temperature region
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper presents the results and methods used for determining of probability of cleavage fracture toughness of ferritic reactor steel in transition temperature area. The steel tested in this study is steel know as ...
Influence of the addition of different radiopacifiers and bioactive nano-hydroxyapatite on physicochemical and biological properties of calcium silicate based endodontic ceramic
(Elsevier Sci Ltd, Oxford, 2021)
The purpose of this study was to investigate the influence of different radiopacifiers on the physicochemical and biological properties of novel calcium silicate based endodontic ceramic enriched with bioactive nanoparticulated ...
Chaotic fruit fly optimization algorithm
(Elsevier, Amsterdam, 2015)
Fruit fly optimization algorithm (FOA) is recently presented metaheuristic technique that is inspired by the behavior of fruit flies. This paper improves the standard FOA by introducing the novel parameter integrated with ...
Ergonomic design of crane cabin interior: The path to improved safety
(Elsevier Science Bv, Amsterdam, 2015)
Many procedures in the development process of crane cabins today are still based on the specific experience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large ...
Fatigue crack growth in locking compression plates
(Elsevier Sci Ltd, Oxford, 2022)
Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. ...
Fatigue crack paths in light aircraft wing spars
(Elsevier Sci Ltd, Oxford, 2019)
Different cracks paths in three different wing spar designs are analysed (differential, integral and optimized integral) to explore how those cracks paths affect fatigue life estimation. First, numerical analysis was carried ...
Evaluation of true stress-strain diagrams for welded joints by application of Digital Image Correlation
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Digital Image Correlation (DIC) is applied to evaluate stress-strain diagrams for welded joints in two different ways. The first one is based on the measures strains along the welded joint, including all 3 zones of interest, ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
Microstructure and fracture of alloyed austempered ductile iron
(Elsevier Science Inc, New York, 2006)
An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these ...
Ductile-to-brittle transition of ferritic steels: A historical sketch and some recent trends
(Engineering Fracture Mechanics, 2023)
The phenomenon of ductile-to-brittle transition in ferritic steels has been a ubiquitous research challenge for the last 50 years. The characterization of this problem using the fracture mechanics concept, from the earliest ...
