An Analytical Model for Stress and Curvature Prediction of a Strip Leveling Process

An analytical model of a steel strip under alternate bending/reverse bending during roller leveling process is developed. A combined isotropic/kinematic hardening implemented through parameter. formulation the change effective stress as function strain cyclic loading with developed to predict distributions and residual curvature efficiently accurately. Dissimilar commonly used assumption one contact point between stripe rolls, an radius modelling wrap-around characteristics proposed. arc around roll described by model. oscillatory behavior observed when range intermesh setting considered. The added may enhance accuracy in predicting curvatures. can be suggested obtain flat after leveling.
