Creasing behavior of corrugated paper board

This paper presents an experimental and numerical study on creasing behavior of corrugated paper boards. Experiments have been carried out on corrugated paper board and its constituent papers. Finite element simulations have been carried out on a plane-strain model, incorporating Hill’s plasticity criterion. The finite element simulations are found to be in good agreement with experimental observations up to initial buckling. The study presented here is intended to help in determining the optimum creasing depth to prevent cracking of paper boards during creasing and folding operations while manufacturing packaging boxes
