The changing rule of the deformed zone and non-deformed zone in the process of bending the vee parts is analyzed.

Sample mark is skillfully marked in hard-deformation zone using heat - resisting paint to insure the accuracy and truthfulness of sample.

On the base of defining regulations,the lead as stock,the course of rolling of H-Beam was simulated,the parameters of length and width in flange and web's zone were analyzed,and the vector distribution rules of friction force in different deformation zone during steady rolling was obtained.

In this paper , an energy modification method introducing a factor m to modify lateraldisplacement distribution of metal at exit of deformation zone in plate/strip rolling , for more pre-cise determination of lateral displacement distribution is described.

Computer simulation software of three-dimensional deformation zone for seamless tube cross rolling process with a function of three-dimensional graph display has been developed on the basis of geometrical models, which provides a basis for analysing deformation zone, setting up and optimizing process parameters.

The changing rule of the deformed zone and non-deformed zone in the process of bending the vee parts is analyzed.

Application of the theory of deformation area to forging production;

So far, numerous tracking approaches based on region deformation have been proposed and the chosen region-based features are mostly special visual information such as mean-color and texture.
