The LEicester Finite Element model for Rolling (LEFER), presented in t
his paper, has been developed to predict strain, strain rate, stress a
nd temperature distributions during hot rolling of steels and aluminiu
m alloys. The model has also been extended to include a constitutive m
odel with a strain function, which depends on the strain, strain rate,
stress and temperature, so that material data are used directly in th
e computations. As an application of this model, the laboratory hot ro
lling of AA1200 aluminium alloy has been modelled to compare with temp
erature measurements and visioplasticity data.
