Numerical-Experimental Determination of Stress and Deformation State in Connecting Lugs with the Effect of Contact Area Size
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The present paper describes numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. The research is based on structural elements of ...
Zadovoljstvo stipendista-povratnika životom u Srbiji / Life satisfaction of returnee scholarship holders in Serbia
(Institut društvenih nauka - Centar za demografska istraživanja, Beograd, 2019)
Educated and talented people drive progress in every country. That’s why no country can neglect these people; that would mean losing one’s own potential. This paper emphasises the importance of educating scholarship students ...
Numerical analysis of fatigue crack growth of hip implant
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Fatigue crack growth in hip implant has been analysed using the extended finite element method. Toward this aim, the three-dimensional finite element model is created and used in ABAQUS and Morfeo/crack add-in for ABAQUS ...
Procedure for Creating Personalized Geometrical Models of the Human Mandible and Corresponding Implants
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The greatest challenge in engineering of human mandible implants lies in its customization for each patient individually, by adapting them to the patient's anatomical, morphological and physiological characteristics. This ...
Structural integrity assessment from the aspect of fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2019)
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Repair of cracks detected in cast components of vertical kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
Creep crack growth behavior of p91 steel weldments
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i. e. secondary creep process. Therefore, creep crack growth tests were ...
