Application of the Newmark Analysis Method in Stability

Joseph Valentin Boussinesq (1842-1929) was a French physicist and mathematician. He was a professor of differential and integral calculus at the Faculty of Sciences of Lille (1872–86), and professor of physics and mechanics at Sorbonne, Paris (1886). In 1883, he solved the problem of stresses produced at any point in a homogeneous, elastic, isotropic soil medium as the result of a point load applied on the surface of an infinitely large half-space.
