【Abstract】 The rule of the stress-strain curve which was obtained from the experiment of the static plain compression on the typical triple wall corrugated fiber board was analyzed, and the nonlinear mathematic model was built according to the curve sectionalized by a linear line, a sine curve and a tangential curve. The model parameter was identified from the experimental findings and the fitting accuracy was discussed. The modeling method used can improve the experiment result. Especially, it makes it possible to quote the nonlinear character of material into the computer optimum design of the packaging structure.更多还原
