The roots of FEA can be traced back to the early 1940s when mathematicians and engineers began developing numerical methods for solving complex physical problems. However, it wasn't until the 1950s and 1960s that the concept of finite element analysis started taking shape.
In the early 1940s, engineer Vladimir Hrennikoff laid the groundwork for FEA by introducing the "stiffness method" for analyzing structures. This method involved dividing complex structures into smaller, manageable elements and analyzing their behavior using matrix algebra. Hrennikoff's work set the stage for the development of modern FEA techniques. In the late 1950s, Ray W. Clough and Richard D. Kunt independently expanded upon Hrennikoff's work. They developed methods for analyzing structures using matrix equations, which became the foundation for modern finite element analysis. Their contributions marked a significant step towards practical applications of FEA in engineering design.
In the 1960s, John Argyris played a pivotal role in advancing FEA by introducing the concept of "substructuring." This technique involved analyzing complex structures by breaking them down into smaller substructures and then assembling the results to obtain an overall solution. Substructuring significantly improved the efficiency and accuracy of FEA simulations. Based on his research, during the 1960s, NASA utilized early forms of FEA to analyze the structural integrity of spacecraft components, including those used in the Apollo program. FEA played a crucial role in ensuring the safety and success of missions, helping to predict how materials and structures would behave under the extreme conditions of space travel. In the 1970s, Boeing used FEA extensively during the development of the Boeing 747 aircraft. FEA simulations helped engineers analyze the aircraft's structural integrity, predict stress distribution, and optimize its design for safety and efficiency.
FEA has evolved significantly since its inception, with continuous advancements in algorithms, computational power, and software tools. It's now a standard practice in engineering. It is practically used in all industries in the development, in science and technology. Along with standardized analyses that have been performed for a very long time, we are facing new challenges and application opportunities.
