 On the basis of modern models and methods of deformable solid mechanics using the methods of finite and boundary elements, theories of hydroelasticity, thermal conductivity and thermoelasticity, as well as optimal design methods, fundamental and applied research in the field of power engineering, petrochemical and aerospace industries have been carried out. Methods for calculating the strength and dynamics of hydraulic unit covers during operational and emergency loading, taking into account hydroelastic effects and a pre-stressed state, a method for dynamic analysis of shell structures with various-shaped partitions partially filled with liquid under pulsed and seismic loading, and a method for calculating the strength of multilayer glazing of aircraft and ground transportation have been developed. A technique to minimize mass and stress in layered structures and shells under impulse force loads which takes into account geometric constraints and strength constraints has been developed. The results of the study of the stress-strained state, vibrations and optimization of the covers of hydraulic turbines, tanks with liquid under impulse loads, glazing of vehicles under unsteady force and thermal loads are obtained; their strength is evaluated. The scope is power engineering enterprises and aerospace industry of Ukraine and other countries of the world.
