“…The second one was the bond criterion of stress. [14][15][16] Metals could be bonded as both materials being plastic stage and the normal pressure in the interface being up to or larger than the deformation resistance of harder layer material. Therefore, this criterion was adopted in this article because the normal stress and the flow stress of the interface at certain temperature and strain rate could be determined.…”

“…Zhang and Yang 12 built a twodimensional (2D) FEM model to predict bond results based on a bond criterion for laminated composites. Lin and colleagues [13][14][15] established a 3D thermal-elastic-plastic-coupled FEM model, and results containing deformation, the equivalent strain, shear stress, residual stress, and the rolling force were obtained. Zong and Zhang, 16 Dong and Wu, 17 and Xu and Zhang 18 determined the minimum relative reduction for perfect bonding by the FEM simulation of single-pass roll bonding process.…”

This article describes an investigation into interface bonding research of 316L/Q345R stainless clad plate. A threedimensional thermal-elastic-plastic model has been established using finite element analysis to model the multi-pass hot rolling process. Results of the model have been compared with those obtained from a rolling experiment of stainless clad plate. The comparisons of temperature and profile of the rolled stainless clad plate have indicated a satisfactory accuracy of finite element analysis simulation. Effects on interface bonding by different parameters including pre-heating temperature, multi-pass thickness reduction rules, rolling speed, covering rate, and different assemble patterns were analyzed systematically. The results show that higher temperature and larger thickness reduction are beneficial to achieve the bonding in vacuum hot rolling process. The critical reduction in the bond at the temperature of 1200°C is 28%, and the critical thickness reduction reduces by about 2% when the temperature increases by 50°C during the range from 1000°C to 1250°C. And the relationship between the minimum pass number and thickness reduction has been suggested. The results also indicate that large covering rate in the assemble pattern of outer soft and inner hard is beneficial to achieve the bond of stainless clad plate.

“…Zhang and Yang (2011) proposed a bond criterion for laminated composites fabricated by hot rolling and simulated the hot rolling process by finite element methods. Lin and Huang (2000b) simulated three different degrees of reduction to analyze the states of shear stress on the upper aluminum strip and lower copper strip close to the contact face. Qin et al (2014) performed shearing and peeling tests to evaluate the bonding results.…”

Purpose This study aims to reduce the warping deformation of the stainless composite plate after removal strake by using a finite element method. A three-dimensional thermo-mechanical coupled elastic-plastic finite element model has been suggested by using ABAQUS to simulate the multi-pass hot rolling of stainless composite plate. Design/methodology/approach A three-dimensional thermo-mechanical coupled elastic-plastic finite element model has been suggested by using ABAQUS to simulate the multi-pass hot rolling of stainless composite plate. Warping deformation rules of 316L/Q345R stainless composite plate after removal strake have been analyzed. Moreover, the influences of some different rolling parameters on this deformation have been discussed. Findings The warping deformation just varies in the range of cladding ratio from 0.1 to 0.25. Therefore, cladding ratio does not have a great influence on warping deformation. Originality/value The results show that higher heating temperature, larger final thickness and less rolling passes are beneficial for reducing the warping deformation.

“…Hwang et al [1] performed an analytical and experimental investigation into the bonding behavior of complex sandwich sheets at the roll gap. Lin and Huang [2] performed three-dimensional finite element simulations based on a thermo-elastic-plastic coupled model to analyze the deformation of flat bimetallic strips during symmetrical rolling under the assumptions of an elastic roller and non-isothermal temperature conditions. Tzou [3] used a Coulomb friction model and a slab analysis technique to investigate the stress field in pre-bonded sandwich sheets during cold rolling.…”

Three-dimensional DEFORMTM finite element simulations are performed to analyze the plastic deformation of heterogeneous sandwich sheets during rolling. The finite element code is based on a rigid-plastic model and the simulations assume that the rollers are rigid bodies and that the deformation-induced change in temperature during rolling is sufficiently small to be neglected. The rolled product is assumed to comprise a central sheet of either A3003 or A6063 aluminum alloy sandwiched between upper and lower sheets of A1100 aluminum alloy. The simulations examine the effects of the sheet thickness and reduction ratio on the maximum effective stress, maximum effective strain, Y-direction load, and maximum damage induced within the rolled product. The simulation results for the final thicknesses of the three layers in the rolled sandwich sheet are compared with the experimental measurements. Overall, the results presented in this study provide a useful insight into the deformation mechanisms involved in the rolling of heterogeneous sandwich sheets.
