1. Efecto del cambio en el camino de deformación en la formabilidad de chapas de acero DP-780 y zinc Zn20
ABSTRACT The Forming Limit Diagram (FLD), frequently used to characterize the formability of sheet metals, is determined by assuming proportional loading histories up to the onset of necking. However, the limit strains are highly affected by strain-paths changes, which are very usual in real metal forming processes. The aim of this work is to analyze the eff

2. Métodos temporales para determinar deformaciones límite en chapas metálicas
ABSTRACT The forming limit diagram (FLD) –broadly used to characterize sheet-metal formability– is made by means of strain measurement over the surface of stretched samples and the subsequent determination of limit-strain values associated with the onset of necking. Currently, researchers can make strain measurements with digital image-correlation analys

3. Estudo comparativo da estampabilidade da liga de aluminio AA1050 partindo de placas obtidas por vazamento direto e bobinas obtidas por vazamento contínuo. / Comparative study of the deep drawing alloy AA1050 from plates obtained by direct casting and coils obtained by continuos casting.
Stampability of aluminum alloys is a subject of interest to several industrial sectors because they are largely used in the fabrication of several parts and components. The choice is based upon the stampability and the relative manufacturing capability in relation to other aluminum alloys that contain larger amounts of alloying elements and, consequently, hi

4. Study on formability in hydroforming steel sheets tailored welded blanks / Estudo da conformabilidade na hidroconformação de recortes de chapas de aço soldados a laser
The increasing number of vehic1es and a more rigorous environmental legislation, are forcing automobile industries and research centers to develop new materials and manufacturing processes to the production of parts with higher mechanical properties, better formability and sheet thickness reduction, without comprirnising the rigidity and structural stability
