Working capacity of aluminum alloys in structure elements

Abstract

Mechanical properties of specimens were researched for model analysis of stress-strain behavior in the stress concentration zone for plate structures using aluminum alloys. Traditional and new structure materials including Russian (1915T and 1565ch) and foreign (6082 – Russian analogue AD35) developments with different alloyage systems (Al-Mg, Al-Mg-Si and Al-Zn-Mg accordingly), strengthening methods, corrosive resistances and welding capacities are studied. Strain and fracture resistance is shown for axial and eccentric tension and for impact bending in the temperature range from -70 to +20°C. Acquired results allow us to designate loads reasonably for structure design using aluminum alloys and estimate their durability.

Influence of welding on aluminium alloy AW6082-T6 strength

“…Following [1,2] we researched welding influence on short duration loading resistance of aluminium specimens made of semi-finished products of aluminium alloy 6082 based on alloying system Al-Si-Mg.…”
