Cracks path growth in turbine blades with TBC under thermo – mechanical cyclic loadings

T. Sadowski, P. Golewski

Blades of combustion turbines are extremely loaded turbojet elements, which transmit operative energy onto a rotor. Experiences of many years indicate, that cracks initiation and propagation in the blades during the operation time can…

Finite-element simulation of residual stresses induced by laser shock peening in TC4 samples structurally similar to a turbine blade

Anastasiia Kostina, Maxim Zhelnin, Sathya Swaroop, Alena Vedernikova, Mariia Bartolomei

This study is devoted to the investigation of residual stresses distribution (RSD) in a TC4 sample treated with laser shock peening. The study placed special emphasis on analyzing the RSD at the part of the samples structurally similar to…

Stress intensity factors for mixed-mode crack growth in imitation models under biaxial loading

Rustam Yarullin, V.N. Shlyannikov, I.S. Ishtyriakov, M.M. Yakovlev

In this study a procedure to stress intensity factors calculation for imitation models made of titanium alloy is described. In service fatigue cracks are detected in a disk and blade “dovetail type” attachment. On the base of this…
