The goal of work is constructing and basing of new models, methods and algorithms of finding the optimization parameters of heterogeneous structures elements in the conditions of the hard thermal and stresses loading, contact interaction and combined types of aggressive influence, and developing scientifically based methods of decrease material capacity of contemporary engineering constructions with taking into account complicating mechanical factors. Research methods: analytical, numerical and experimental methods of deformable solid mechanics. Results of work are consist of developing new mathematically based and mechanical correct optimization models of heterogeneous shells constructions with unsteady parameters in the conditions of contact interaction, of hard thermal and stresses loading and combined types of agressive influence. The results of work are used in the airspace building, medicine, metallurgical industry for decreasing material capacity. Product Description popup.authors popup.nrat_date 2020-04-02 Close
