Doświadczalna analiza efektu pamięci materiału poddanego plastycznemu odkształceniu

Experimental analysis of the memory effect is discussed for plastically prestrained aluminium alloy. Tests were carried out using plane specimens cut out in different directions from previously plastically deformed sheets. Experimental results show that if two various loading paths have different initial sectors and a common final sector, the influence of these initial sectors on the yield surface is the smaller, the longer is the final common sector.
