Abstract
Approximate optimal design and weight minimization problems are propos ed, making use of mixed-interpolated finite elements methods. The desi gn variables - i.e., the thickness of tile plate and tile stiffness of tile foundation are approximated by piecewise affine functions. The s olvability of the approximate problems is proved and some convergence analysis is presented.
