First,effective strain rate for three-dimensional forging is expressed in terms of two-dimensional strain rate vector,then,strain rate ratio function and direction cosine of this vector are determined,and finally the inner-product of the vector is term by term integrated.

The Application of Pro/E Secondary Development Technology in 3D Forging Die CAD;

Analysis for flat tool pseudo-three-dimensional forging by MY criterion considering the effect of external zone

In this paper,the rigid viscoplastic element formulas are derived according toa new constitutive relationship,and are applied to the numerical simulation of three-dimensional plastic compression of metals.

: Based on the Backhaus three-dimensional baroclinic model, this paper simulate the effect of southwest wind field on the Pearl River estuary, and compares it to the effect when there is no wind.
