| Abstract: | This paper presented an investigation of material properties of aluminium extrusions 6082(T5). The true stress-strain curve and anisotropy parameter ,r 0,r 45 and r 90 were determined. In order to give a criterion for the study of the bending fracture, the forming limit diagram of the extrusion was established by the uniaxial tension test. |
