Tray forming operation of paperboard: A case study using implicit finite element analysis

Abstract The possibility to perform advanced forming operations of initially plane paperboard paves the way making products like food trays, plates, cups and other containers as a part shifting towards circular bioeconomy. As ongoing efforts expanding product range using paperboard, we performed analyses operation simulations. An implicit non‐linear finite element model is built more accurately than previous studies simulate tray process paperboard. Two different commercial paperboards are investigated. use an solver enabled inclusion creasing pattern into geometry blank resolving formation wrinkles during forming. material data extracted from tensile test curves investigated was fitted Hill's plasticity with difference in tension compression accounted for subsequent failure evaluation. results showed that creases vital getting correct shape formed important decreasing risk failure. also friction has big impact on hence stress levels, therefore supports means lowering between holder operation. A stochastic approach proposed determine probability boards. evaluation consistent field observations. developed enables precise simulations
