| Abstract: | Plastic deformation of the wheel and rail in contact is analyzed with the elasto plastic theory. A concept of shakedown limit for wheel and rail materials under elasto plastic condition is proposed. Based on this concept, the plastic deformation of the contacting wheel rail is predicted by means of calculation. |

| Keywords: | wheel rail relation plastic deformation shakedown limit |
