Burlayenko V. The elaboration of method for the simulation of creep and durable strength of thin-walled structural elements under cyclic loading

Shallow shells and plates. The elaboration of method and software for the creep and durable strength calculations at the conditions of combined action of static and cyclic loads, establishment the law research of a dynamic creep and damage of structures. Theoretical: method of asymptotic expansions, numerical: finite elements method, Euler's, Cholecky's, frontal, Jacoby's, experimental methods, experimental equipment, computer. The method of calculation of a static and dynamic creep with damage considerations is elaborated. Numerical and experimental data on a dynamic creep and damage are obtained, the law of influence of a cyclical load on the creep, stress-strain state, forming and fracture are established. The method of calculation of creep on the basis of new equations of a dynamic creep at the complex stresses state is created. Technique, programs and results of calculations are used in scientific research themes of Ministry of education of Ukraine in KSAUF and KSPU. Power and airspace machinery, mechanical engineering.
