MODELING AND VERIFIC ATION OF THE CLADDIN G TUBE BEND

This paper deal with modeling of the bend of cladding tube and follow ing r ealisation of a modeled bend. FEM modeling gave possibility for modeling many combination of the bending parameters and than pick the best combination of a bending parameters. Results, like shear stresses and deformations, obtained from model are listed. Best combination of working parame ters was used for the manufacture of a bend. The bended tube was subjected to analysis. The results shown that there are no imperfections like cracks or layers delamination. Results of investigation by SEM including measurement of chemical distribution aro und interface of cladding tube are shown. For investigation and modeling FEM Software PMD ® (Package for Machine Design), SEM microscope Jeol JSM 7600F, optical microscope Nikon Eclipse MA 200 w ere used.
