Effect of heat generation due to plastic deformation on behavior of material in surface layer at sliding friction.
A modified macroscopic model taking into account frictional heating and additional heat generation in the material surface layer due to its plastic deformation is used to simulate sliding friction of materials having different ability to work hardening. It is shown that the consideration of additional heat generation affects the thermal state and shear deformation in the surface layer provided that the ability of the material to hardening is within the certain range. The comparative calculations performed with and without consideration of additional heat generation are used to show the qualitative and quantitative differences in the processes of the heating and plastic deformation of the surface layer in these cases
