This paper concerns the development of a primal-dual algorithm for shakedown analysis of 3D structures using the face-based smoothed finite element method (FS-FEM). The algorithm based upon the von Mises yield criterion and a nonlinear optimization procedure is used to compute simultaneously both the upper and lower bounds of the plastic collapse limit and the shakedown limit. This calculation provides a useful tool to estimate the accuracy of the solution and to ensure the convergence of the proposed algorithm. In the FSFEM, the strains are smoothed over the smoothing domains associated with faces of elements. Using constant smoothing function, only one Gaussian point is required for each smoothing domain ensuring that the total number of variables in the resulting optimization problem is kept to a minimum compared with the standard finite element formulation.

This article is concerned with parametric continuous-time convex programs pertaining to a class of concave-convex fractional optimal control problems with linear state constraints. Some basic properties of parametric continuous-time convex programming problems are derived. These properties will provide an important foundation for constructing a parametric computational procedure for solving the concave-convex fractional optimal control problems with linear state constraints.
