The paper presents some researches about the influence of the plastic deformation kinetics, respectively, of the relative rate of drawing, the force parameters and on the resistance and plasticity mechanical characteristics, during the ultrasonics drawing of the cylindrical symmetry metallic wires able to be hardened, when the die is placed in the maximum of the waves oscillations and it is activated along the drawing direction. The modifications of the force parameters and of the resistance and plasticity mechanical characteristics are considered to be based on “the ultrasounds surface effect” accepting the phenomenon of the mean friction reversal in a complete time of the oscillation, T - Severdenko’s model. As a reduction measure of the mean friction at the metal-tool contact is the coefficient φ..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
