| Popis: | A numerical approach to investigation of static and dynamic characteristics of fuel reservoir and surge-protection capacity with cracks in welded joints of their walls has been proposed. Mathematical modeling of the nonlinear behavior of the complex shell structure has been performed under the action of static vertical loading using the software complex of finite element analysis. The models of cracks with different length within vertical and horizontal welded joints of shell walls have been developed. The influence of cracks on the stress-strain state and stability of the fuel reservoir as well as the surge-protection capacity has been investigated. The dynamic characteristics of the structure have been determined, the influence of cracks on the frequencies and the modes of their natural vibrations has been evaluated. |
