“…As mentioned before, metals at room temperature exhibit kinematic hardening and therefore, cold strip levelling simulations are mostly performed based on material models incorporating a kinematic hardening component. For example, the nonlinear Chaboche kinematic hardening model was used by Garcia et al [11] for simulation of tension levelling of 1 mm thick DP1000 steel. Silvestre et al [12] used Chaboche combined hardening model for roll levelling of 2 mm thick MS1200 and DC04 steel strips.…”

Flatness is an important quality parameter of heavy plates and it is generally achieved through cyclic elastoplastic deformation of the plate in a hot roller leveller following the rolling and cooling processes. To investigate and optimize the hot plate levelling (straightening) process, Finite Element (FE) simulations are widely used. Generally, flow curves with isotropic hardening are used for hot plate levelling simulations. However, the plate material might exhibit kinematic hardening, due to the load reversal that is seldom considered due to laborious high temperature cyclic material characterization. The current work aims at understanding the implications of considering kinematic hardening within hot heavy plate levelling simulations. Hot uniaxial and cyclic material characterization of S355 steel at 1000 °C is performed and the corresponding stress-strain curves are extracted. Using an inverse modelling technique, the associated isotropic and kinematic hardening models are calibrated. The cyclic data showed that the S355 steel exhibits kinematic hardening and the Chaboche kinematic hardening model is suitable to model this behaviour. Hot levelling simulations of plates with isotropic and kinematic hardening models showed a noticeable difference in the roll reaction forces and local curvature of the plate during the process while the resulting flatness of the final plate is not very sensitive to the material model for the investigated scenarios.

“…Three spatial limit hexagons of plasticity 1-2, 2-3 and 1-3 as the intersections of the limit prism of plasticity and three coordinate planes are also marked in Figure 3 . The axis of the respective area is identical to the so-called hydrostatic axis which passes through the origin of the coordinate system and is equidistant from all three major axes [ 24 , 25 , 26 , 27 , 28 , 29 ].…”

In exact analyses of bodies in the elastic–plastic regime, the behavior of the material above critical stress values plays a key role. In addition, under cyclic stress, important phenomena to be taken into account are the various types of hardening and the design of the material or structure. In this process, it is important to define several groups of characteristics. These include, for instance, the initial area of plasticity or load which defines the interface between elastic and plastic deformation area. The characteristics also include the relevant law of plastic deformation which specifies the velocity direction of plastic deformation during plastic deformation. In the hardening condition, it is also important to determine the position, size and shape of the subsequent loading area. The elasto-plastic theory was used for the analysis of special compliant mechanisms that are applied for positioning of extremely precise members of the Compact Linear Collider (CLIC), e.g., cryomagnets, laser equipment, etc. Different types of deformation hardening were used to simulate the behavior of particular structural elements in the elastic–plastic regime. Obtained values of stresses and deformations may be used in further practical applications or as default values in other strain hardening model simulations.

“…They found that both factors can influence the microstructure and mechanical properties of leveled steel strips, indicating the possibility of improving steel strip properties by adjusting the elongation and intermesh during tension leveling. Garcia et al [3] applied different work hardening models to the FE analysis of tension leveling and concluded that the introduced hardening rule is an important input in the FE analysis of tension leveling since it influences simulation results. Although previous investigations have clarified some factors affecting tension leveling such as the arrangement and intermesh of leveler rolls and the work hardening properties of materials, further investigations must be conducted 1) to reveal much more factors that affect tension leveling to provide a deeper insight into this process, 2) to improve the accuracy of tension leveling simulation, and 3) to realize consistency analysis of tension leveling and subsequent sheet metal forming considering the tension leveling history.…”
