COMPARISON OF BARRELING EFFECT IN COMPRESSION TESTS OF TWO KINDS OF SPECIMENS USING THE FINITE ELEMENT METHOD

This paper shows a comparative study of two types of forging specimens (Rastegaev and Stauchprobe) in order to obtain stress flow curves at compressive loads with a wide range of temperature, by using a Finite Element Analysis. The main aim is to determine which specimen shows the minimum barreling phenomena under compression at different temperature condition. After the data were obtained, a comparative analysis leads to conclude that the...
