On a special feature of optimal design of structures operating in aggressive environment.

Extensive numerical studies of the dependence of the stress-strain state influence function on corrosion process speed with regard to the stiffness of the optimized structure have been performed. For the optimum design of structures interacting with an aggressive environment, application of the method of repeated identification of mathematical models of corrosion fracture is proposed. Theoretical aspects of the problem are discussed. The procedure of definition of parameters of the mathematical model of the corrosion fracture providing evolutionary transition of the structure into the optimum state is provided.
