<p>Given the considerable performance disparity and asynchronous elongation of the two components, severe warping deformation frequently emerges during the roll-bonding process of Cu/Al laminates. This phenomenon poses a major technical challenge in the production of high-quality composites. Currently, no existing model is capable of quantitatively and precisely predicting warping height through theoretical calculations. In the present study, the symplectic elasticity method is utilized to analyze the bending deformation characteristics of Cu/Al laminates under initial strain conditions. An analytical model is developed to determine the warping height mathematically and derive the accurate solution. Results indicate that the warping height of the rolled laminates is proportional to the square of the plate length and the elongation difference between the upper and lower surfaces of the laminates. Reducing the elongation difference under the same plate length can effectively minimize the warping height. Comparing the rolling experimental results with the analytical calculations reveals that the maximum relative errors are 8.17 % at a 35 % reduction ratio, 8.68 % at a 40 % reduction ratio, and 7.73 % at a 40 % reduction ratio. The maximum relative error does not exceed 9 %, while it is just around 5 % under general conditions. These findings confirm the accuracy of the mathematical model. The study provides a theoretical foundation for predicting and controlling the warping height in the rolling of high-quality metal laminates.</p>
