Computer simulation of fatigue, creep and thermal-fatigue cracks propagation in gas-turbine blades
Artem Semenov, Sergey Semenov, Anatoly Nazarenko, Leonid Getsov
Izvirni znanstveni članek
Oznake: fatigue;creep;thermal fatigue;crack;C*-integral;turbine blades;finite element simulation;
Methods and computational algorithms for determining the growth rate of fatigue creep and thermal-fatigue cracks are considered. The rate of crack growth is dependent on the stress-intensity factor (or J-integral) for fatigue, on the C*-integral for creep and on the stress-intensity factor (or J-int ...

A failure criterion for single-crystal superalloys during thermocyclic loading
Leonid Getsov, Artem Semenov, Alexander Staroselsky
Izvirni znanstveni članek
Oznake: single crystals;cyclic and axial loading;thermal fatigue;failure criteria;
The accumulation of deformation affects the lifetime of a monocristal submitted to low cyclic mechanical and thermal loading. An analytical method was developed considering the damages due to cyclic and axial plastic and creep deformation. The method was checked with tests in vacuum on specimens of ...
