The paper analyzes the interaction between woven fabric and needle in the integrated piercing process of orthogonal laminated woven fabrics, proposes and establishes fiber bending elongation and elongation breakage model,and talks over the structure parameters influencing fiber bending elongation.

Theoretical Investigation into Continuous Tension Leveling Process of Metal Strip (2) --Analysis on the tension leveling process of elastic-perfect plastic metal strip over the first bending roll;

This paper expounds the characteristics of tension leveling and application in copper fabricating industry,and studies the selection and optimization for the main technological parameters.

In this paper, the method to calculate the energy consumption and variation of tension during tension leveling of metal strips is investigated and formulae for the elastic-perfect material are suggested which are useful for the design of a continuous tension leveler.

This paper analyses the spring back of car's middle sliding rail on stretch bending.
