Some History of Finite Element Analysis

Historically, we can think of FEA as beginning in 1678 when Robert Hooke determined that force is proportional to a constant multiplied by a strain (Hooke s law) [Pg.52]

The evolution of FEA really began in 1940 with Hrennikoff developing truss-based numerical methods to analyze general structures. A timeline would show [Pg.52]

1943 Robert Courant proposes breaking a continuous system into triangular elements. [Pg.52]

1950 Boeing uses analog computers, triangular elements, and matrices to analyze surfaces. [Pg.52]

1960 Dr. Ray Clough coins the term finite element—an entity that can model three-dimensional strain. [Pg.52]
