Incremental sheet metal forming is a forming process where a sheet is formed into the final workpiece of desired shape by a sequence of small incremental deformations (Jeswiet et al., 2005b). Process has gained the attention of researchers because it does not require dedicated tooling and hence suitable even for single piece production. However, the process takes longer processing time. Looking at the research potential, the process has been studied by various researchers from the point of thinning band (Hussain, Hayat and Gao, 2008), force (Filice et al., 2006), power consumption (Ingarao et al.,2012), accuracy (Duflou et al.,2007), and surface finish (Attanasio et al.,2006).

In order to obtain a large deformation solution, several intermediate configurations are assumed between the initial (reference) and the final solution, and the large deformation is obtained as the combination of the incremental deformations for all the intermediate configurations. The schematics of the reference (), the intermediate or the known deformed () and the current or the unknown deformed () configurations is presented in Figure 1 [52].

From the above simple review, to the best of our knowledge, rare references about wave propagation in the layered cylindrical structures with sectorial cross-sections under initial stress are available. In this paper, based on the “Mechanics of Incremental Deformations”, the double-orthogonal polynomial series method is exploited to investigate the effect of initial stress on guided waves propagating in the layered cylindrical structures with sectorial cross-sections. The traction free boundary conditions are assumed in this paper.
