The Coefficient of Restitution in the Plastic Deformation Process
Résumé
In the analysis of dynamic processes and plastic deformation which appear on the
forging and die forging equipments dint the shocks (forging hammers and screw
presses), it is use frequently theoretical study of de collision from theoretical
mechanics.
Both the calculus of the efficiency of the forging hammer and the calculus
of the damping system appear a coefficient “k” known as coefficient of
restitution. This paper describes the physical pregnancy and the manner to
evaluation of this coefficient of restitution.
