In this work, the results from a series of experiments are presented to determine the effect of specimen geometry-dimensions on the compression behavior of AA6066Al  alloy. Three geometries of compression specimens have been used; solid, tapered and collar. For each geometry, the compression tests have been carried out under dry and lubricated conditions. The experiments have been conducted at various aspect ratios: Ho-Do; 1.5, 1.25, 1, 0.75, and 0.5. The results showed that the circumferential strain εθ of the cylindrical specimens increases as the axial strain εz increases. For collar specimens, the values of local strain εz are inversely proportional to the total axial strain, while for tapered specimens, the local circumferential strains εθ are very close to the total circumferential strain.
