Laserbeam-welded overlapped tubular joints made from structural steel St35 (S235 G2T), artificially hardened aluminium alloy AlSi1MgMn T6 (EN AW 6082 T6) and self-hardening aluminium alloy AlMg3.5Mn (EN AW 5042) were investigated under combined proportional and non-proportional axial and ...
equipped with a leading set of pipe inspection equipment, strictly implementing various testing indexes, and ensuring the reliability of product quality 100%. Strictly follow the ISO9001:2008 quality management system and control the production process. Product standards are equivalent to international ...
Accordingly, the elastic-perfectly plastic material model is selected, and it is acceptable for the comparative study, the ultimate strength of panels that are all made of 6082-T6 alloy. The SHELL181 element is employed. The element size of 25 mm × 25 mm is selected based on the results ...
In the T6 and T651 tempered varieties, alloy 6082 machines well and pro- duces tight coils of swarf when chip breakers are used. General applications of this class of alumini- um include highly stressed applications, trusses, bridges, cranes and transport applications. The chemical composition is...
In particular, starting from the definition of the effective width of the equivalent continuous beam, the plastic resistance of the effective cross-section is evaluated as a function of the ultimate material strength by means of a coefficient (1/k), which takes into account both the actual ...
the single lap joints were obtained with thin plates of 6082-t6 alloy and a high strength epoxy adhesive of two components (araldite 420 a/b). the strength of weldbonded joints was found to be significantly higher than equivalent spot welded joints. numerical models were developed replicating ...
equivalent plastic strain plots for all materials based on the representative tests. By use of 2D-DIC, the major principal strain field ε1(x,y) can be calculated as a function of the overall straining of the specimen, where x and y are the coordinates in the extrusion and transverse ...
The average grain size was expressed by the area-weighted mean value of the equivalent diameter of individual grains using D‾=∑WiDi∑Wi, to account for the considerable scatter of individual grain size between columnar grains and equiaxed grains. To assess the weld mechanical properties, ...
Recently several groups of aluminium alloys are applied in car manufacturing, among them for example AA5754 H22 and AA6082 T6. Concerning for example AA5754 (AlMg3) alloy, it is widely used in sports cars. This alloy has medium strength among aluminium alloys. AA6082 is commonly used for ...
These data also suggest that even friction stir welds with root flaws exceed the design life for equivalent fusion welds set out in the draft Eurocode 9 and that a higher rating may be warranted. Limited test results produced for this work need to be supplemented with a wider range of tests...
