ОЦЕНКА РЕСУРСА ЛОПАТКИ ТУРБИНЫ С УЧЁТОМ ВЗАИМОДЕЙСТВИЯ СТАТИЧЕСКОГО И ТЕРМОЦИКЛИЧЕСКОГО НАГРУЖЕНИЯ

Abstract

For new materials, information on the elasticity and strength characteristics necessary for calculating the stress-strain. state of the turbine blades is limited. In these conditions, there is a need for theoretical and semi empirical methods for calculating the elastic, strength and creep characteristics. The proposed theoretical methods based on forces of interatomic interaction calculation. The classical methods based on the hypothesis of continuity do not allow calculating the material strength and thermo physical properties.
