In an epoch-making paper entitled "On an approximate answer for the bending of a beam of oblong cross-section less than any process of load with precise connection with issues of focused or discontinuous loading", bought by means of the Royal Society on June 12, 1902, L. N. G. FlLON brought the concept of what used to be thus known as through LovE "general ized airplane stress". within the similar paper FlLO~ additionally gave the basic equations which show the displacement (u, v) when it comes to the complicated variable. the 3 uncomplicated equations of the idea of KoLOsov (1909) which used to be hence built and better via MUSKHELISHVILI (1915 and onwards) could be derived without delay from Filon's equations. The derivation is indicated through FlLO)!E~KO-BoRODICH. even supposing FILO)! proceeded immediately to the true variable, traditionally he's the founding father of the trendy conception of the appliance of the complicated variable to airplane elastic difficulties. the tactic was once constructed independently via A. C. STEVEXSOX in a paper bought via the Royal Society in 1940 yet which used to be no longer released, for safety purposes, till 1945.
