Keywords: creep models, damage, turbine blades

A creep phenomenon needs to be taken into account during strength calculation of turbine blades that work for a long duration under wide range of stresses and temperatures. Experimental data on creep resistance usually are limited. Determination method of stress-strain state (SSS) kinetics based on limited experimental data is proposed.
