TY - GEN A1 - Sprekels, Jürgen A1 - Tiba, Dan T1 - Optimal design of mechanical structures N2 - We prove new properties for the linear isotropic elasticity system and for thickness minimization problems. We also present very recent results concerning shape optimization problems for three-dimensional curved rods and for shells. The questions discussed in this paper are related to the control variational method and to control into coefficients problems.
