Original Formulation of the Finite Element Method

by Ray W. Clough, Emeritas Univ of California, United States,

Document Type: Proceeding Paper

Part of: Computer Utilization in Structural Engineering


Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members of the Structural Dyanmics Unit at the Boeing Airplane Company. It is noted that the central feature of the procedure that was developed is the evaluation of the stiffness properties of structural elements based on assumed sets of displacement interpolation functions.
