“…The generation of inclined waves is essentially an inclined buckling deformation formed by unevenly distributed residual stresses in the strip, so the method of assuming stress functions in theory of elasticity is used to solve for the stress distribution before the strip produces inclined waves (the solution for the front tension distribution of inclined wave) [5,18] . And since the direction of the inclined wave forms an obvious angle with the strip width direction compared with the conventional wave, as shown in Figure 2.…”

In the strip cold rolling process, the inclined wave defect is an atypical flatness defect that can adversely affect the subsequent coating process. In order to investigate the causes of inclined wave defects, the tension stress distribution in the cold rolling process was investigated by using the method of assuming pre-buckling load distribution and stress boundary conditions in this paper. According to the study, the load distribution that produces the inclined wave defect was obtained, and the load distribution was verified by finite element simulation. The results show that the obtained load distributions are consistent with the conditions for the generation of inclined wave defects. On this basis, the influence laws of several parameters on the inclined wave defects are obtained through rolling test and simulation analysis, and the effective suppression of strip inclined wave defects is achieved.

“…The dislocation solutions were then employed to perform integral equations for the analysis of a strip weakened by multiple cracks with any configuration and arrangement. In [23] the large deflection evaluating of the thin strip under practical condition of residual stress after cold rolling was investigated using the incompatible von Krmn equations as the governing equations. The problems for the cracked bodies were solved in [24], [25].…”

The mixed problem for the fixed semi-strip is investigated in this article for the three cases of the applied mechanical load. The solution of the boundary problem is reduced to the solution of the singular integral equation (SIE) with regard to the unknown displacements derivative. Three cases of SIE are investigated: when the mechanical load is applied on the center of the semi-strips edge, when the mechanical load is distributed near the left lateral side and when the mechanical load is distributed on the whole semi-strip's edge. In the first case SIE is solved by the using of the orthogonal polynomials method. In the second and third cases the characteristical equations to SIE are constructed, and the SIE are solved with the help of the generalized method. The stress state of the semi-strip is investigated for the three cases. Keywords semi-strip • singular integral equation • fixed singularity • orthogonal polynomials method • generalized method
