Application to DC-05 electrogalvanized steel (UNE in ISO 10130)}, volume={43}, url={https://revistademetalurgia.revistas.csic.es/index.php/revistademetalurgia/article/view/61}, DOI={10.3989/revmetalm.2007.v43.i2.61}, abstractNote={In this work a methodology to investigate deep drawing quality steel sheets deformation tendency under multiaxial deep drawing stresses has been proposed. The method consists in assaying a sheet in a wedge die in order to introduce a pure shear estate in the material. 0º, 45º and 90º rolling directions are selected in the assays, and transversal strain is the variable considered in them. A strain coefficient ‰ has been defined in order to evaluate thickness variations in the test. Almost no changes in thickness have been registered and this indicates that strain carried out in the test is similar to that taking place in deep drawing. The stress necessary for practice a certain plastic deformation is obtained too and a potential function between them is formulated. Indicators presented in this work are compared to anisotropy and strength coefficients obtained in normalized tensile tests. These results allow us to justify the steel behaviour in the cup deep drawing processes related to ear forming.}, number={2}, journal={Revista de Metalurgia}, author={Miguel, V. and Calatayud, A. and Ferrer, C.}, year={2007}, month={Apr.}, pages={146–156} }
