摘要

The paper is devoted to the experimental characterizationCharacterization of the room temperature mechanical response of 5052-H32 aluminum alloyAluminum alloy. MeasurementsMeasurements of the initial textureTexture of this material, showed that it displays a mild anisotropy in the plane of the sheet. Uniaxial tension tests were conducted for seven orientations in the plane of the sheet to quantify the effects of textureTexture on the macroscopic plastic properties. Local strains were monitored using Digital Image Correlation. Irrespective of the orientation, it was found that this material displays Portevin–Le Chatelier (PLC) effects. The challenges in the determination of Lankford’s coefficient for a material exhibiting PLC are discussed and addressed.
