广义双τ^2屈服准则

Yielding Criterion of General the Twin τ2

建立了金属材料的广义双τ2 屈服准则 ,讨论了准则的屈服线形状 ,通过误差分析 ,给出一种能较好代替Mises准则的加权双τ2 屈服准则 .

General twin τ 2 yielding criterion of matal material is established.The shape of the yielding ling,is discussed. On error analysis, the weighted twin τ 2 yidlding criterion is obtained and mises yielding criterion can be ralaced by it.
