Abstract：

Meshless method has been developed and sprung up in recent years.RKPM(Reproducing Kernel Particle Method)program was used to simulate the upsetting procedure of the cylinder when its ratio of the height and diameter was 1.0 and the friction factor was from 0.05 to 0.5.The quantitative relationship among the sample crowning in the upsetting experiment,the friction factor of the contact surface,the deformation velocity and the temperature was giv- en.This relationship could be used to estimate the friction factor of the contact surface.Finally,the feasibility of the meshless method was verified by the upsetting experiment in different friction conditions.
