Multi-component sandwich panels have emerged in recent years for new engineering and structural uses. These structures have been modeled as large deflections and multi-component sandwich beams subjected to pure bending with its ends with monolithic section. In the case of curved beams subjected to pure bending, a linear distribution has been considered. Different end-section reductions and sandwich–monolithic transitions have been analyzed with a finite element analysis model developed. Finally, the results of the finite element model are validated using an experimental test.
