Before the development of electronic computers, it was not feasible to perform analyses of stresses in soil masses for other than assumed linear elastic soil behavior. Now, however, due to the availability of high-speed computers and powerful numerical analytical techniques such as the finite element method developed by Clough (4), it is possible to approximate nonlinear, inelastic soil behavior in stress analyses.
