The present work treats of the application of the numerical
limit analysis (NLA)to geomechanics problems. The soil or
rock mass is considered as conventional continuous and
Cosserat continuous. A mathematical programming (MP)
problem is obtained through the application of the mixed
formulation of limit analysis and the finite elements mesh.
The application of this methodology in the Cosserat
continuous (2D) supplies linear programming (LP)
problems and in the conventional continuous (2D and 3D)
nonlinear programming (NLP) problems. The solution of the
problem of MP was through the LINDO (LP), LINGO (NLP),
MINOS (NLP) and LANCELOT (NLP) programs. It was also
implemented nonlinear algorithms -Quasi-Newton feasible
point method- and -Han-Powell-.The formulation is validated
in problems whose analytic solution is known or in
experimental data. These examples show the speed and the
effectiveness of NLA for the determination of the collapse
load and of the mechanism of rupture of the problem.
