Effect of biomaterial on integrity and life of artificial hip / Uticaj biomaterijala na integritet i vek veštačkog kuka
(Faculty of Mechanical Engineering, University of Belgrade, 2016)
Hip replacement is a surgical procedure in which parts of the hip joint are removed and replaced with artificial parts, which is known as the prosthesis. Metallic alloys are used for prosthesis, its femoral head and stem ...
Temperature fields and residual stresses in welded joints of high-strength steel / Temperaturska polja i zaostali naponi u zavarenim spojevima čelika povišene čvrstoće
(Univerzitet u Beogradu, Mašinski fakultet, 2014)
The effect of the residual stresses and strains is one of the most important parameters in the structural integrity assessment. A finite element model is constructed in order to simulate the multi passes mismatched submerged ...
Initial plastic deformation and residual stress influencing the welding joint behavior in the presence of cracks / Uticaj inicijalne plastične deformacije i zaostalih napona na ponašanje zavarenog spoja u prisustvu prsline
(Univerzitet u Beogradu, Mašinski fakultet, 2015)
The full-scale model of penstock was produced using weldable high strength low alloyed steel (HSLA) Sumiten 80P (SM 80P). Steel SM 80P belongs to HT80 steel with tensile strength above 800 MPa and yield strength above ...
Uticaj koncentracije napona i pojave prsline na preostali radni vek biomaterijala za rekonstruktivne pločice / Influence of stress concentration and crack initiation on remaining life of biomaterials for reconstructive plates
(Univerzitet u Beogradu, Mašinski fakultet, 2021)
Biomaterijali namenjeni za izradu ortopedskih rekonstruktivnih pločica su boljih mehaničkih karakteristika u odnosu na kosti, a ipak u velikom broju slučajeva dolazi do otkaza pločica usled zamornog oštećenja. Jasno je da ...
Primena parametara elasto-plastične mehanike loma na procenu integriteta velikih sfernih rezervoara / Application of parameters of elastic-plastic fracture mechanics for integrity assessment of large spherical storage tanks
(Univerzitet u Beogradu, Mašinski fakultet, 2019)
U radu se analizira integritet konstrukcije velikog sfernog rezervoara za skladištenje tečnog amonijaka koji je izložen dejstvu unutrašnjeg pritiska, koji je izrađen zavarivanjem segmenata gornjeg i donjeg dela polusfernog ...
Micromechanical fracture analysis of high strength steel weldments / Mikromehanička analiza loma zavarenih spojeva čelika povišene čvrstoće
(Univerzitet u Beogradu, Mašinski fakultet, 2013)
The industrial application of high strength steel in structural welded components has increased the demand for understanding the ductile failure behavior of this type of welded materials. Therefore, integrity assessment ...
Application of fracture mechanics parameters to residual life assessment of welded pipes exploitation under fatigue loading / Primena parametara mehanike loma na procenu preostalog veka zavarenih cevi u uslovima zamornog opterećenja
(Faculty of Mechanical Engineering, University of Belgrade, 2021)
Thesis presents a study of the fatigue life of welded steel tubes made of API J55 steel, using the parameters of the fracture mechanics obtained on the basis of experimental research. At the same time, analyses the integrity ...
Условна оптимизација дискретних система аутоматског управљања применом потпуне преносне функције / Conditional optimization of discrete-time control systems using the full transfer function
(Univerzitet u Beogradu, Mašinski fakultet, 2023)
