- A shell problem ‘highly sensitive’ to thickness changes

- Book Title / Journal: International Journal for Numerical Methods in Engineering
- Year: 2003 , Volume: 57 , Series:
- Structural Analysis
- Keywords: shells ; asymptotic analysis ; finite element solution
- Description
- In general, shell structural problems can be identied to fall into one of the categories of membrane-dominated, bending-dominated and mixed shell problems. The asymptotic behaviour with a well-defined load-scaling factor shows distinctly into which category a given shell problem falls. The objective of this paper is to present a shell problem and its solution for which there is no convergence to a well-dened load-scaling factor as the thickness of the shell decreases. Such shells are unduly sensitive in their behaviour because the ratio of membrane to bending energy stored changes signicantly and indeed can uctuate with changes in shell thickness. We briefly review the dierent asymptotic behaviours that shell problems can display, and then present the specic problem considered and its numerical solution using nite element analysis.

- Measuring convergence of mixed finite element discretizations: an application to shell structures
- J.F. Hiller ; K.J. Bathe
- Book Title / Journal: Computers and Structures
- Year: 2003 , Volume: 81 , Series:
- Structural Analysis
- Keywords: Finite elements ; shell structures
- Description
- We consider the problem of assessing the convergence of mixed-formulated finite elements. When displacementbased formulations are considered, convergence measures of finite element solutions to the exact solution of the mathematical problem are well known. However when mixed formulations are considered, there is no well-established method to measure the convergence of the finite element solution. We first review a number of approaches that have been employed and discuss their limitations. After having stated the properties that an ideal error measure would possess, we introduce a new physics-based procedure. The new proposed error measure can be used for many different types of mixed formulations and physical problems. We illustrate its use in an assessment of the performance of the MITC family of shell elements.

- Towards improving the MITC9 shell element
- K.J. Bathe ; P.S. Lee ; J.F. Hiller
- Book Title / Journal: Computers and Structures
- Year: 2003 , Volume: 81 , Series:
- Structural Analysis
- Keywords: Shell elements ; MITC9
- Description
- The objective in this paper is to present some results regarding the predictive capabilities of the MITC9 shell element when the tying points in the element are changed. The MITC9 element is a general nine-node shell element based on the formulation approach of using mixed-interpolated tensorial components. Different tying points are very simple to implement and are not decreasing the computational efficiency of the element. Hence, the use of the ‘‘best’’ tying points is clearly of value.

- An evaluation of the Lyapunov characteristic exponent of chaotic continuous systems

- Book Title / Journal: International Journal for Numerical Methods in Engineering
- Year: 2003 , Volume: 56 , Series:
- Structural Analysis
- Keywords: stability analysis ; Lyapunov characteristic exponent ; non-linear dynamics ; dynamic stability
- Description
- A procedure to calculate the Lyapunov characteristic exponent of the response of structural continuous systems, discretized using nite element methods, is proposed. The Lyapunov characteristic exponent can be used to characterize the asymptotic stability of the system dynamic response, and it is frequently employed to identify a chaotic behaviour. The proposed procedure can also be used in the stability characterization of uid–structure interaction systems in which the focus of the analysis is on the behaviour of the structural part.
