Abstract
Numerical solutions of nonlinear stress analysis problems are traditio nally based on the finite element method. Here, we introduce a new for mulation based on the application of the 'initial stress' computationa l process to the spectral collocation approximation. We also consider domain decomposition methods in order to handle complex geometries and non-smooth data. We present several numerical results concerning benc hmark problems in geomechanics.
