This paper proposes a novel method for determining the initial strip width for thick-walled
steel pipes in roll forming. The method introduces three criteria to define the minimum initial …

The geometrical characteristic of products is one of the crucial quality indicators in the cold
roll forming process. In this process, an appropriate flower pattern for rolls is vital to achieve …

The size effect in microscale occurs due to the presence of a limited number of grains in
deformation area and affects the mechanical behavior of the material. Based on this …
