Abstract: The effect of the strain accumulation by changing the number of rolling passes on the rolling force, structure and mechanical properties of austenitic Cr-Ni-Ti stainless steel with different carbon contents has been studied. An increase of the number of passes for a given overall reduction was found to have a beneficial effect on tensile properties while maintaining adequate ductility. [..] Read more

Abstract: At the beginning of the production of body parts from Al-alloy, there was a requirement to experimentally verify its suitability for their production. This alloy is characterized by a combination of various stress-deformation properties influencing the non-uniform plastic flow of the material, especially during deep drawing of complex shaped drawn parts.

Abstract: Folding is a common industry practice. In this work we have studied the influence of some parameters such as (the radius of curvature of the matrix, the coefficient of friction between the punch and the specimen, the play between matrix and punch, the thickness of the specimen and the mesh of the specimen) on the deformations of the different zones of the specimen, by a numerical simulation of U-bending using the ABAQUS calculation code.The studied parameters will prove to be of relevant use for the design of the parts from the metal sheets, through the bending forming process.
