Lateral mechanics of an imperfect web
Abstract
A model describing the lateral mechanics of an imperfect web has been derived which brings forward information on the much debated fourth boundary condition. The model is based upon a generalized beam theory. Calculations show that a web with CD profile in stiffness and/or frozen-in strain (camber) will shift towards the low tension side. The deflection increases with increasing tension and decreasing stiffness. The dependence upon tension is related to the stiffness profile. A web with a constant profile in stiffness, but with a varying profile in frozen-in strain, has a very weak influence of tension upon deflection.
