Some reliability issues in the current practice of finite element analysis are enumerated. These issues pertain to the selection of the appropriate mathematical model and the accurate solution of this model using finite element procedures.
The reliability of the mathematical model used can be assessed by considering a hierarchically higher-order mathematical model. The reliability of the finite element solution requires use of reliable finite element procedures and the evaluation of error measures. Some industry analysis cases are mentioned to show the importance of the reliability issues discussed.
The material given in this paper largely represents a summary and synthesis of ideas and results presented previously by the author.
