- 論文の詳細を見る
The forming limit diagrams of proportionally prestrained brass sheets are experimentally determined for a combination of uniaxial and equi-biaxial tensions. From these FLDs and the theoretical ones predicted using a new plastic constitutive equation previously proposed by one of the authors (Gotoh) and a local necking condition, the n-th power hardening, Voce and modified Voce hardening laws are compared to determine the most suitable one for the brass sheet. Furthermore, the dependence of the FLDs on sheet thickness of the brass sheet is discussed.
