Abstract
The method of complementary energy is a general method of structural mechanics. The basic law was stated by F. Engesser in a paper in 1889. He extended Castigliano’s law of least work to apply beyond the range of Hooke’s law by replacing work by complementary work, which is an integral of distance times increment of force. Engesser’s paper is little known.Keywords
