Tribological aspect of selecting filler metal for repair surfacing of gears by hardfacing / Tribološki aspekti izbora dodatnog materijala kod površinske reparacije zupčanika tvrdim navarivanjem
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
Analysis of repaired gears made of case-hardening steel 20MnCr5 by hardfacing method is presented in this paper. Hardfacing repaired gears are tested on the closed power circuit device with variation of the torque value. ...
Determination of fatigue crack growth parameters in welded joint of HSLA steel / Određivanje parametara zamornog rasta prsline kod zavarenih spojeva od HSLA čelika
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
The structural integrity and operational safety of welded pressure vessels primarily depends on the behaviour of weldments. In spite of all efforts in material production and improvements in welding techniques, including ...
Failure analysis of chain bracket / Analiza loma spojnice lanca
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In spite of numerous and expensive research in the field of fatigue and fracture and regular control of end products, cracks occur every day in all fields of human activity. This paper describes failure analysis of chain ...
Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model / Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In this paper, two micromechanical models: the Gurson-Tvergaard-Needleman (GTN) model and Complete Gurson Model (CGM) are used to predict ductile fracture initiation of two different welded specimens, SE(B) and C(T). The ...
Numerical simulation of the plunge stage in friction stir welding / Numerička simulacija faze uranjanja kod zavarivanja trenjem mešanjem
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
This paper investigates the plunge stage using numerical modeling. A three-dimensional finite element model (FEM) of the plunge stage is developed using the commercial code ABAQUS to study the thermo-mechanical processes ...
