Subject of this paper are deformation mechanisms in pre‐tensioned elastic belts, which are wrapped around rollers carrying elastic layers that support the belts over part of their width. By means of analytical models and the finite element method the corresponding deformations of the belts are predicted. Special emphasis is put on the effects of the nonlinear (contact) boundary conditions in the vicinity of the lateral edges of the roller. The continuum finite element simulations provide reference solutions, and, furthermore, serve as an accurate means for predicting the contact stress distribution, whereas the semi‐analytical solutions allow for an inexpensive and quick investigation of several parameter combinations. The high quality of the semi‐analytical model can be judged by the excellent agreement of the obtained results with the reference finite element results. (© 2005 WILEY‐VCH Verlag GmbH & Co.
