Non-uniform deformation after prestrain
Fernandes, José-Valdemar; Menezes, Luis F.; Rodrigues, Dulce M.; Chaparro, Bruno M.; Vieira, Manuel F.The deformation behaviour of prestrained metal sheets is analysed in this work. The non-uniform deformation observed during reloading in tension was studied, by following deformation in different regions of the samples. It takes into account the presence of geometrical defects in the samples and explains the importance of mechanical behaviour. A simplified analysis was used, to model the behaviour in tension of...
