Abstract：

As a numerical method, BEM is superior in less calculating\|working and accurate prediction, so it is often used in analyzing plastic problem. In this paper, two dimensional rigid\|plastic boundary element method is presented, with which flow velocity of rolling\|piece in flat\|rolling is calculated and neutral surface is verified ,all these demonstrate the validity of BEM in rolling.
