V. A. Andreyachshenko Faculty of Nanotechnology and Metallurgy, Karaganda state technical University, Karaganda In the paper there is studied stressed-and-strained state formed in a billet by fullering in a tool with movable elements. It is determined that compressing stresses prevail in the studied tool; they improve the quality of the processed billets. Even maximum main normal stresses have ...

Fullering process is a type of open die forging. In this research, elongation and maximum sideways spread in final shape of a billet after the first blow of a fullering process are predicted by designing a back propagation multilayer perceptron neural network. Several experiments are conducted using lead as the model material. Billets with three different square cross-sections are used in these...
