Identification of Material and Structural Parameters of Corrugated Board in Production and Converting Processes

Modern engineering trends prioritize sustainable materials, with corrugated board at the forefront, analysed from Multiscale and Multiphysics perspectives. This study delves into modelling corrugated board, structured as a composite of flat and corrugated papers, requiring assessments of orthotropic properties and structural geometry. We investigate the mechanical responses of corrugated board, considering production processes. Through detailed mechanical testing and numerical homogenization, our research focuses on identifying parameters in structural topology, mechanics and fabrication processes. Employing inverse analysis and artificial neural networks, the study develops a comprehensive methodology for parameter identification and understanding the mechanics of corrugated board. This approach enhances quality control in production and offers insights for future corrugated board research.
