The purpo e of the present study is to obtain the rolling-stress distributions due to the rectilineal and circular grooved rolls. In the first report, the author investigated the three-dimentional distributions of rolling stress in regard to flat rolling process. In grooved rolling process, generally, most of materials are rolled restricting the lateral spread due to the roll sides. So, it is very difficult to find the general solution of rolling stress as compard with flat rolling process. The author adopted a simple experimental result and obtained the three-dimentional stress distributions during the rolling in the case of the materials were rolled at the entry side holding the plane.
