Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja / Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model
(Institut za ispitivanje materijala, Beograd, 2011)
U ovom radu, primenjena su dva mikromehanička modela: Gurson-Tvergard-Nidlman (GTN) model i Potpuni Gurson model (CGM) za procenu inicijacije duktilnog loma kod dve različite zavarene epruvete, SE(B) i C(T). Uticaj mismečinga ...
Numerical analysis of constraint effect on ductile tearing in strength mismatched welded cct specimens using micromechanical approach
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
In this paper, constraint effect on ductile fracture initiation and propagation has been studied. Three-dimensional finite element analyses of mismatched welded joints made of high strength steel, have been performed for ...
Influence of crack length on ductile fracture initiation in welded joints with one and two weld metals
(Trans Tech Publications Ltd, Durnten-Zurich, 2011)
Among various micromechanical models for ductile fracture analysis using local approach, those based on the Gurson plastic flow criterion have been intensively developed in the past three decades. However, their application ...
