The aim of this work is to present variational formulations for the limit analysis problem and solution procedures using the finite element method and mathematical programming techniques.
The variational formulations are presented in three versions: static, kinematical and mixed. These formulations are derived from the proposition of the constitutive relationship in the form of conjugate pseudopotencials. Finite element discretizations are proposed for each of the three continuous problems.
Two iterative mathematical programming algorithms are prosed to solve the problem. These algorithms can be applied to the plastic behavior described by a set of linear or non-linear yield functions. Limit analysis in plane strain, plane stress and axissymetric solids are considered in the numerical examples.
