| Finite Element Analysis (FEA)Introduction to FEA - History
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.
This method was termed ‘Finite Element Analysis’ by Dr. Ray Clough of
the University of California in 1960, who built on earlier work by
others.
The first ‘proper’ FEA code, NASTRAN, was developed in 1965 for NASA by
MacNeal & Schwendler, who later set up MSC. NASTRAN uses 'h' elements,
but in the 1980's Rasna Corporation released a commercial code,
MECHANICA which used 'p' elements. These are elements which have a much
higher order polynomial equation describing their behaviour and this
brings certain advantages, such as the ability to follow curved
surfaces, be more flexible and allow the writing of automatic
convergence routines without re-meshing.
Elite Consulting chose MECHANICA (now owned by PTC) in 1993 and we have used it ever since. For more information on How Mechanica Works, click here. Examples of Typical ProjectsExamples of project work using Pro/MECHANICA Structure include:-
