Аннотация:The results of unique experimental studies of the strength and service life of a metal-composite high-pressure tank are presented. The study is aimed at analyzing the fracture mechanisms and evaluating the strength characteristics of the structure. The technique included tests of full-scale samples of the tank for durability under short-term static, long-term static, and cyclic loading with internal pneumatic pressure. The generalized test results and data of visual measurements, instrumental and acoustic-emission control of deformation processes, accumulation of damage, and destruction of full-scale tank samples are presented. The strength and the stiffness of the structure exposed to internal pneumatic pressure are analyzed. The types of limiting states of the tanks are established experimentally. Variation in the stress-strain state of the tank under cyclic and prolonged static loading is considered. The specific features of the destruction mechanism of the metal-composite tank are determined with allowance for the role of the metal liner strain. The calculated and experimental estimates of the energy potential of destruction and the size of the area affected by destruction of the tank are presented. Analysis of the test results show that the tank has high strength and resource characteristics that meet the requirements of the design documentation. The experimental results are in good agreement with the results of the numerical calculations and analysis of the stress-strain state and destruction mechanisms of the metal-composite tank.
