In this paper,a finite deformation finite element algorithm of plane strain mode was presented The forging process of tractor chain was simulated by using this algorithm,much information about metal forging process were abtained,they were in good accordance with the experiments It is shown that this algorithm is suitable for simulating the metal forging process
