The development of modern mechanics in recent years has made many importanf progresses in the concepts and methods for nonlinear large deformation mechanics[1][2][3] etc, The present paper is aimed to show how the natural co-moving system method and Stokes-Chen's deco mposition theorem can be effectively applied asy mptotically to solving problems of finite defor mation elasto-plasticity by inverse asy mptotic method for engineering design purpose.Rigid punch problem is examplified in the paper.
