摘要: In many industrial processes, geometric strip defects may be generated by buckling due to excessive residual stresses and these are difficult control. Usually have complex distributions so that with shapes appear. rolling, strips fabricated under tension, which has an impact on the shape amplitude of defects. This tension can hide completely or partially increase evolve during release. this work we calculate flatness stresses, without using a shell finite element model based asymptotic numerical method (ANM).
