EXPERIMENTAL-STUDY OF THE DEFORMATION LAWS OF HEMISPHERICAL PARTS IN THE COMPOUND-FORMING PROCESS

In this paper, the critical condition which is used to distinguish the deformation patterns between stretching and drawing has been advanced in accordance with the investigation of the compound-forming process of hemispherical parts. Also, the compound-degree equation expressed b y the centre-line length of the cross-section of the parts is derived during the compound-forming of hemispherical parts in terms of the con cept of the compound-degree proposed by the authors in this paper. Thi s work will help in determining the properties of the procedure and en suring the quality of the products. (C) 1998 Elsevier Science S.A.
