Abstract

The paper deals with behavior of scalar functional serving for optimiza- tion of eigenstrains with stochastically perturbed and correlated values in a laminated cylindrical structure from composite materials. The eigenstrains in layers are required for several reasons, as is improvement of bearing ca- pacity of the laminated cylinder, creep, time delay in construction of large structures, etc. For expressing the relation between stresses and eigen- strains in each layer the transformation field analysis. [3], serves. Recently. in [4] and [5], optimum eigenstrains or optimum eigenstresses were solved under assumption that these quantities had stochastically perturbed and non-correlated values. In this paper the optimum eigenstrains are searched, for which the cost functio
