The Bending Stiffnesses of Corrugated Board
نویسندگان
چکیده
In this work, an analytical study on the bending stiffnesses of corrugated board has been performed. Formulations to calculate the bending stiffnesses D11, D22, D12, and D66 of the equivalent plate representing the corrugated board have been established, and then compared to expressions suggested by other investigators. Several methods for modeling the shape of the corrugated orthotropic medium material have been considered including sinusoidal, arc-and-tangent, and elliptical representations. An extension of the membrane analogy method has been used to calculate the torsional rigidity D66 of the corrugated board In addition to the shape of the corrugated core material, the developed stiffness formulations require the thicknesses and material properties of the component paperboards as input.

Apparatus for Evaluating Stability of Corrugated Board under Load in Cyclic Humidity Environment
The strength of a corrugated container is usually determined and reported as crush strength under progressively increasing top-to-bottom compressive load. The test is performed in seconds in a controlled constant temperature and relative humidity environment. However, a dynamic strength test under controlled conditions cannot account for the reduction in load-carrying ability inherent in the ex...

Factor A: postharvest treatments with six levels (1. untreated (control), 2. washing with chlorine, 3. dipping (5 minutes) in calcium chloride (CaCl2), 4. dipping (5 minutes) in bavistin and rinse in clean water, 5. hot water treatment and 6. tap wat...
متن کاملEffect of Relative Humidity on the Optimum Flute Shape for Corrugated Fiberboard
Container stacking strength is an important performance requirement of corrugated fiberboard. The objective of this study is to examine theoretically how fluting geometry affects fiberboard strength and stiffness under standard relative humidity (RH) and high RH conditions. The fluted medium in a corrugated fiberboard is modeled as a connection of curved arc and straight flank segments passing ...
متن کاملLoad-displacement properties of lower cervical spine motion segments.
The load-displacement behavior of 35 fresh adult cervical spine motion segments was measured in compression, shear, flexion, extension, lateral bending and axial torsion tests. Motion segments were tested both intact and with posterior elements removed. Applied forces ranged to 73.6 N in compression and to 39 N in shear, while applied moments ranged to 2.16 Nm. For each mode of loading, princip...
