ABSTRACT
The paper presents a beam theory for composite girders consisting of two beams joined
together with an adhesive layer. The height of the bottom beam is considered variable. The
governing equations are suitable for formulation of a shape optimization problem in terms of
control theory. The use of Pontryagin’s maximum principle enables finding an optimal solution
satisfying necessary optimality conditions. The presented optimization approach allows
for including issues which cannot be accounted for by commercial topology optimization
software. The introduced theory provides an estimated solution, which is then validated by
an analysis of a 3D finite element model.
