Optimization of the finite element model of Corrugated Cardboard based on an orthotropic material constitutive model
PROCEEDINGS OF THE 2017 5TH INTERNATIONAL CONFERENCE ON MACHINERY, MATERIALS AND COMPUTING TECHNOLOGY (ICMMCT 2017)（2017）
Abstract
This paper presents a study on improvement of the finite element model of corrugated cardboards. There is one shortcoming in modeling the stiffness of such cardboards in literature: neglect of the material non-linear effect of cardboards and cannot predict the peak load. A finite element method was applied to overcome this shortcoming - particularly by adopting an orthotropic material constitutive model.
