John Lyell Sanders

John Lyell Sanders, Jr. (born September 11, 1924 in Highland , Wisconsin , † October 7, 1998 in Sudbury , Massachusetts ) was an American mechanical and aerospace engineer at Harvard University . He is best known for his mathematically sound work on the mechanics of missiles , including the theory of the non-linear behavior of shells .

Life

Sanders earned in 1945 at Purdue University with a degree in Aeronautical Engineering ( Aerospace Engineering ) and was called the next day. He served two years in a unit for cryptography of the US Army . He then earned a Masters at the Massachusetts Institute of Technology with a thesis on the theory of coiled shells and a Ph.D. in 1954 with Daniel Charles Drucker at Brown University. , The title of his dissertation was Plastic Stress-Strain Relations Based On Infinitely Many Plane Loading Surfaces . The thesis was about the irreversible deformation of metals under overload.

From 1954 to 1958, Sanders worked for the National Advisory Committee for Aeronautics , NASA's predecessor organization . Here, too, he dealt with the shell of aircraft fuselages and missiles . In 1958 he received a call to Harvard University , where he worked mainly with Bernard Budiansky and George Carrier . Fred Abernathy , Howard Emmons , Sydney Goldstein , Max Krook and Richard Kronauer also belonged to the group of mutually enriching mathematically oriented engineering scientists (in the broadest sense) .

In 1971, Sanders was elected to the American Academy of Arts and Sciences .

John Lyell Sanders was married to Mary Jane Wade. The couple had three children.
