Influence of internal volumetric imperfections on the tearing resistance curve of welded single edge notched tension (SENT) specimens Universiteit Gent
The acceptance of volumetric weld imperfections is subjected to workmanship guidelines, which are subjective quality criteria loosely related to fitness for purpose assessments. However, the relative impact of such imperfections may be accentuated in fracture toughness tests, given the relatively small dimensions of the test specimens. This study analyses the impact of weld volumetric imperfections on the outcome of fracture toughness tests. ...
Crack driving force calculation in arbitrarily shaped defects based on 3D non-destructive evaluation and finite element analysis Universiteit Gent
Influence of weld porosity on crack size estimations in Single Edge Notched Tension (SENT) testing of steels : a numerical study Universiteit Gent
Influence of small volumetric flaws on the measurement of crack growth and tearing resistance in SENT tests Universiteit Gent
This study evaluates the influence of volumetric discontinuities on the SENT tearing resistance curve as measured using DCPD and UC techniques. In order to do that, a series of SENT tests was carried out on specimens containing small drilled holes in different locations to simulate the presence of volumetric weld flaws. In addition, porous welds were produced by robotic Gas Metal Arc Welding (GMAW). Welding parameters were fine-tuned in order to ...
Proof of concept of integrating 3-dimensional nde information into finite element analysis Universiteit Gent
Geometrical size effect in the fatigue life predictions of aluminum wires with micro holes using methods of the critical distance Universiteit Gent
Effects of volumetric weld imperfections on the characterization of ductile tearing resistance and its validity Universiteit Gent
De structurele integriteit van gelaste structuren is sterk afhankelijk van hun breuktaaiheid. Om deze te bepalen worden scherp gekerfde proefstukken tot breuk belast en hun gedrag geanalyseerd. Er is een gebrekkige kennis rond de effecten van volumetrische lasimperfecties (bijv. poriën) op het gedrag van deze proefstukken. Bovendien bespreken de huidige normen voor breuktaaiheid niet de geldigheid van tests die zijn uitgevoerd op monsters met ...
