Analysis of the dynamics of the rolling process of multilayer viscoelastic bodies

The paper identifies deformations in layers of laminated composite sheets shaped in the rolling process.Rolling process of layered composites is a dynamic issue, for which the problem is to precisely determine the value of deformations of individual sheet components resulting from differences in their properties.The aim of this work was to determine the impact of delayed viscoelastic effects on increasing the computational accuracy of deformations of metal layers constituting the AlMg+Al1050+M1E layered composite.Three three-parameter Jeffreys models connected in parallel were used to analyze the course of changes in deformation of laminar composite layers.The presented test results refer to the determination of the deformation values in the rolling valley and the zone of delayed viscoelastic effects.The work showed that the solution used contributed to increasing the accuracy of the calculations.
