The paper is devoted to a quite general version of the multicriteria optimal
(minimum volume) design of axisymmetric circular plates. The constitutive material is
considered as elastic perfectly plastic without any ductility limit and the actions are assumed
as quasi-statically variable within a given load domain. In the design problem formulation
different resistance criteria are considered, in order to investigate all the possible structural
limit responses, and for each one a suitably chosen safety factor is chosen. The optimal
design problem is formulated as the search for the minimum structure volume according with
a statical approach. The features of the optimal structures will be studied through the
relevant Euler-Lagrange equations. A numerical application is presented utilizing an
appropriate discretization of the minimum volume problem
