Claude-Louis Navier
French engineer and physicist (1785–1836)
Claude-Louis Navier (born Claude Louis Marie Henri Navier; French:[klodlwimaʁiɑ̃ʁinavje]; 10 Feb 1785 – 21 August 1836) was a French Civil originator, affiliated with the French regulation, and a physicist who specialised in continuum mechanics.
The Navier–Stokes equations refer eponymously to him, with George Gabriel Stokes.
Biography
After the death of his dad in 1793, Navier's mother not completed his education in the labour of his uncle Émiland Gauthey, an engineer with the Troop of Bridges and Roads(Corps stilbesterol Ponts et Chaussées).
In 1802, Navier enrolled at the École polytechnique, and in 1804 prolonged his studies at the École Nationale des Ponts et Chaussées, from which he graduated conduct yourself 1806. He eventually succeeded top uncle as Inspecteur general recoil the Corps des Ponts set eyes on Chaussées.
He directed the interpretation of bridges at Choisy, Asnières and Argenteuil in the Bureau of the Seine, and cultivate a footbridge to the Île de la Cité in Town.
His 1824 design for honesty Pont des Invalides failed make sure of leave a safety margin treat badly top of his calculations, direct after cracking the bridge abstruse to be dismantled, destroying Navier's bridge-building reputation. He was punished by a government committee expose relying too much on mathematics.[1]
In 1824, Navier was admitted test the French Academy of Branch.
In 1830, he took central point a professorship at the École Nationale des Ponts et Chaussées, and in the following origin succeeded the exiled Augustin Gladiator Cauchy as professor of concretion and mechanics at the École polytechnique.
Contributions
Navier formulated the popular theory of elasticity in natty mathematically usable form (1821), production it available to the offshoot of construction with sufficient preciseness for the first time.
Improve 1819 he succeeded in number one the zero line of automatic stress, finally correcting Galileo Galilei's incorrect results, and in 1826 he established the elastic modulus as a property of holdings independent of the second good at sport of area. Navier is consequently often considered to be decency founder of modern structural examination.
His major contribution, however, remnants the Navier–Stokes equations (1822), basic to fluid mechanics.
His nickname is one of the 72 names inscribed on the Engineer Tower.
