Finite Element Analysis of Buckling of Corrugated Fiberboard

چکیده
This paper investigates the relationship between mechanical behaviors and shape of corrugated fiberboard by means of buckling analysis, which is done by FEM (Finite Element Method). Firstly, after analyzing the structure of corrugated fiberboard a single-wall corrugated fiberboard model was built. The buckling load was measured in the ideal condition by linear buckling analysis (eigenvalue buckling analysis). Subsequently, nonlinear buckling analysis of singlewall corrugated fiberboard was performed using the results of the eigenvalue buckling analysis. Finally, a finite element 3-D model of four-layer and five-layer corrugated fiberboard was established using ANSYS parametric design language (APDL) to improve mechanical properties of corrugated fiberboard based on comparing different eigenvalue buckling loads.

Thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. Recent earthquakes, e.g. Hyogoken-Nanbu or Kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. This paper presents a new innovative thin-walled hollow steel column fabricated of corrugated plates, “thin-walled steel columns...
متن کاملFinite Element Method for Static Cyclic Behavior of Steel Shear Wall with Corrugated Plates
The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...
متن کاملComparison of Postbuckling Model and Finite Element Model with Compression Strength of Corrugated Boxes
Conventional compression strength formulas for corrugated fiberboard boxes are limited to geometry and material that produce an elastic postbuckling failure. Inelastic postbuckling can occur in squatty boxes and trays, but a mechanistic rationale for unifying observed strength data is lacking. This study employs a finite element model, instead of actual experiments, to generate experimentally d...
متن کاملBuckling Analysis of Axially Loaded Corrugated Cylindrical Shells
Buckling analyses of heavily corrugated cylindrical shells based on detailed full finite element models are usually computationally expensive. To address this issue, we have proposed an efficient computational method of predicting the onset of buckling for corrugated cylindrical shells which builds on the Bloch wave method for infinitely periodic structures. We modified the traditional Bloch wa...

This work is focused on the finite element study of the energy absorbing behavior of aluminum (corrugated webs). The aim is to study the mechanism of energy absorption in specific metallic structures by understanding these mechanisms. The sine wave web (or corrugated web) structural component constructed of aluminum has been chosen as the specific structural element for this study. The sine wav...
