Digital Analysis of Deformed Corrugated Boxes Using 3D Speckles
During transportation from the manufacturer to the retailer packages are affected by vibrations, shocks, staticand dynamic loads, as well as by changes in temperature and humidity. In order to improve the quality of the packaging towithstand stresses during transportation it is important to know the parameters that characterize the deformation state inthe package. Corrugated boxes are affected by a phenomenon known as mechanosorptive creep, the basics of which arestill not well understood. That is why it is interesting to know how changes in moisture content affect corrugated boxesand how it is possible to prolong the lifetime of transportation packages. This paper presents an attempt to use the whitelight digital photography method for a three-dimensional analysis of the deformation states near collapse of a corrugatedbox during varying humidity, and attempts to obtain characteristic parameters that can be used to describe deformationstates close to collapse. A series of tests using an optical non-destructive testing method are reported and the results fordifferent test configurations are presented. Comparison is made between tests performed at different load levels andclimate conditions. The optical deformation measurement system used for analysis was ARAMIS? (GOM mbH,Braunschweig, Germany). Advantages and disadvantages of working with this system are also described and suggestionsfor future work are discussed.
