BASIC PARAMETERS OF METAL BEHAVIOR UNDER HIGH RATE FORMING

Abstract

Using the dy amic e pa sion of a ring, the uniform elongatio to failure a igh rates of train as been measured for seven materials, by mea uring the c ge in grid pacing on one surface of fractured ring . Values obtaine using a mean initial strain rate of the order of 1000 per second re compared to t e v lues obtained on specim ns pulled to fracture at a mean strain rate of .001 per econ . The yna ic uniform elong tion to fr cture was greater tha the qua i-sta ic v lue for m t rials of low ductility and some hat less than the quasi-static value for the material of high ductili y. 9author)
