Short summary
In this paper, a lined pipe was formed through a drawing process. In double-layered pipes, shear strength is the most important design factor. We verified the effect on shear strength by changing the pipe surface roughness. In order to apply the surface roughness in FEM analysis, the surface roughness was converted to the friction coefficient. Through FEM analysis, we obtained a critical value for the change in shear strength.
