Breslavs'kyj D. Development of the method for сreep and durable strength calculations of cyclically loaded structural members

Structural members. Development of the method for creep and durable strength calculations for cyclically loaded machine elements. The methods are: asymptotical expansions, computer numerical simulation using FEM, predictor- corrector methods, experimental investigations on creep and fracture of specimens and plates in mine-type furnace, by use the units AIMA-5-2, VEDS-10A. Constitutive equations and the method of numerical analysis for cyclic creep-damage at complex stress state are developed, the new laws of cyclic creep and fracture of machine elements are established. The new method of calculations for the first time allows to perform at the design stage the scientifically based estimations of durable strength for cyclically loaded machine elements. The results of calculations and conclusions were used at "Turboatom", NSC KhFTI and ITC "Line". The sphere of use is machine building.
