Abstract

A theoretical analysis of rate sensitive pencil glide is carried out. It can be applied to pencil glide with any set of slip directions, not only 〈111〉, and in any reference frame. As a first application, the behaviour of an isotropic polycrystal deforming by rate sensitive 〈111〉 pencil glide is studied. The present approach is also applied to the prediction of rolling textures with the Taylor model and with the relaxed constraint model. It is shown that the latter is in better agreement with experimental results. The influence of the rate sensitivity index is also examined, and qualitative agreement is obtained with an experimental result for rolling at warm temperatures.
