Parameter analysis on single cold-formed C type steel beam-column connections;

Analysis of stability for cold-formed thin-walled C steel column

Cold-formed thin-walled C steel sections are lightweight materials and suitable for building construction owing to their high structural performance and durability.

Effects of anisotropic yield criteria on the spring-back s FEM simulating of stainless stell sheet s cold-roll forming process;

Inorder to reduce periodicity of cold-roll forming processs and improve the quality of products and me- chanical property the explicit dynamic finite element method with the software of ANSYS/LS-DYNA to simulate the cold-roll forming processs of channel stell,is studied including deforme,stresses and stains in the forming process.

The basic principles and arithmetic of FEM numerical simulation of cold roll forming process are reviewed in this paper,the large structural analysis program ANSYS/LS-DYNA is used to simulate cold-roll forming progress,analyze the simulating results,and gain the theory and technology which are useful to directing real manufacturing.

Cold-roll void forming sheet is an important product in cold-roll forming sheet, which usually includes pipe, square tube, rectangle tube and unusual tube made by special requirements.
