Welcome to Corrugraphics

When box panels buckle into multiple half-waves failure occurs by elastic postbuckling and box strength becomes insensitive to box depth. Squatty boxes or narrow box panels can fail by inelastic postbuckling.

• A quantum leap in box analysis software
• Predict compression strength from paper properties
• Determine the lowest cost linerboard and corrugating medium
• Quantify sustainability objectives
• Work within the Excel environment

In a unique collaboration with the Forest Products Laboratory research on paper as a structural material has been incorporated within modeling software called CODE41. With CODE41 the user can predict box compression strength from stress-strain properties of the constituent paperboards. This software tool will help producers and users of corrugated fiberboard who want to

• Design containers based on the paperboard components
• Determine the most efficient basis weight combination among linerboard and medium components
• Determine how changes in paperboard properties affect box compression strength
• Create a new flute profile for greater box compression strength
• Predict how humidity induced changes to paper affect box compression strength
• Characterize material inputs to other finite element analyses
• Minimize material costs
