| Abstract: | Various existing anisotropic yield criteria for meta l sheet forming are
reviewed and discussed in this paper. A general expression o f elastoplastic constitutive
equations applicable to various yield criteria is d eveloped based on tensor algorithms,
and the explicit expressions for some yield criteria are presented and their codes are
implemented to ABAQUS software. Thro ugh testing the correctness of these expressions is
proved. |
