【 摘 要 】

In this work, tensile tests were first conducted on the paperboard. Then, the in-plane orthotropic elastoplastic model (IPE-Isotropic Plasticity Equivalent model) was implemented in Abaqus software. The advantage of this model lies in its capability to describe the in-plane anisotropic behavior of paperboard by a limited number of material constants. The calibration procedure was handled by inverse identification method on tensile tests. The model was shown to predict satisfactorily in-plane stress-strain behavior for different orientations. Box compression tests (BCT) were conducted to investigate the performance of the implemented model. The predicted deformed boxes and force-displacement curves were compared to the experimental ones, displaying a good agreement.
