Abstract: Sheet rolling is a simple plastic deformation of which, there are many formulas to describe its bite condition, however, there is no rigorous theoretical analysis and result and the applying ranges of these formulas are limited. Although the bite condition is not an important problem in engineering or academy, it is really a term influenced by many factors and it is difficult, maybe impossible to be expressed by an equation. In this paper, by finite element software, the bite condition or the critical friction factor under different thicknesses of AZ31 sheet, rolling reduction, sheet temperature and roller temperature are calculated and with large result data, the change regulation of the bite condition appears which is shown in a colour brick model. This example shows that, avoiding rigorous theoretical analysis, a complex situation can be numerically illustrated well by finite element software.
