Corrugated Fiberboard

This paper investigates the relationship between mechanical behaviors and the 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 based on single-wall 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.

This paper presents a numerical investigation on the behaviour of circular double-skin tubular concrete (DSTC) under concentric loading. The numerical analysis is carried out using a three-dimensional non-linear finite element package (3D-NLFEA). In DSTC specimen, the concrete is enclosed by FRP wraps at the outer tube and circular hollow steel (CHS) at the inner tube. The concrete constitutive model is based on the authors developed plasticity-fracture model which uses a non-constant plastic dilation rate for modelling concrete dilation under compression. The nonlinear buckling analysis is included in the analysis. Random material imperfection is used to induced asymmetric failure pattern. Mohr-Coulomb friction model is used to simulate the contact behaviour between concrete and CHS elements. The results from the FEA are compared with the available experimental results. From the comparison, it can be concluded that the use of the authors plasticity-fracture model is in good agreement with the test results.

Nonlinear Buckling Analysis

An overview of a specific reduced order modelling technique for Finite Element nonlinear buckling analysis of structures under static and dynamic loading is presented. The reduction method applied makes use of an available, well-established analytical perturbation procedure for static buckling and dynamic buckling analysis. This procedure has in the past years been used as the foundation for the development and implementation of a Finite Element framework for reduced order nonlinear buckling analysis. These achievements are reported, including a concise description of the underlying theory and certain characteristic examples. A basic example of a composite plate and other examples related to aircraft applications demonstrate the capabilities of this reduced order modelling framework for nonlinear buckling and dynamic response analysis and illustrate the current status of its development.
