FEA – Finite Element Analysis
History of FEA
Simple problems with simple shapes can be solved by classical methods. Complex problems and complex continuous shapes cannot be solved directly.
Therefore in 1943 Richard Courant (born in Germany, Professor of Maths at New York University from 1936) proposed splitting the shape into triangular segments (later called elements) that could be solved by numerical methods. (He used the Ritz method of numerical analysis and minimization of variational calculus to obtain approximate solutions to vibration systems.)
Dr. Ray Clough of the University of California published a paper in 1956 & later, in 1960 termed the method ‘Finite Element Analysis’.
The first ‘proper’ FEA code, NASTRAN, was developed in 1965 for NASA by MacNeal & Schwendler, & later set up MSC.
Now almost everyone uses FEA to analyse structural problems and by using FEA, Elite Consulting can help you to determine how your design will perform, where problems may arise and how to overcome them.
Elite Consulting has been using FEA for stress analysis for over 20 years to:
- Analyse concepts to help choose the best one.
- Determine load capacity, stress levels and deflections.
- Optimise designs to reduce cost.
- Reducing time to market
- Investigating why components have failed.
