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 ...
Integrity and Life Assessment Procedure for a Reactor
(Elsevier Science Bv, Amsterdam, 2019)
Integrity and life assessment of structural elements or structures subjected to variable loads is necessary in order to define the control interval and removal of damages that occurred during exploitation. Integrity and ...
Risk based analysis of temperature and time effects on brittle fracture of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
Risk based analysis of temperature and time effects on fracture toughness values is applied to different regions of a welded joint made of low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. ...
Relation between impact and fracture toughness of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
The influence of temperature on impact and fracture toughness values in different regions of a welded joint is analysed for low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Standard Charpy ...
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 ...
Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
Numerical Simulation of Fatigue Crack Growth in Hip Implants
(Elsevier Science Bv, Amsterdam, 2016)
In this paper numerical analysis of hip replacement implant behaviour from a fracture mechanics perspective is presented. It is necessary to understand the fatigue crack initiation and propagation characteristics in order ...
Comparative Exemination of the Strengthened and Non-Strengthened NIMONIC Specimens with Laser Shot Peening Method
(Elsevier Science Bv, Amsterdam, 2018)
Laser shot peening (LSP) of material strengthening is nowdays widely used method in various branches of industry. In this paper are presented comparative exeminations of specimen made of NIMONIC and strengthened specimen ...
Finite element modeling of hip implant static loading
(Elsevier Science Bv, Amsterdam, 2016)
In this paper a numerical investigation of replacement implant for partial hip arthroplasty is presented. The long-term stability of hip implants depends, among other things, on the loads acting across the joint. Forces ...
Microhardness and Macrostructures of Friction Stir Welded T-joints
(Elsevier Science Bv, Amsterdam, 2018)
The results of research regarding the friction stir welding process of T-joints are presented in this paper. Experimental welding of two and three aluminium plates were performed in order to obtain T-joints. Microhardness ...
