Abstract

The authors put forward a procedure of creep analysis for variable loading conditions, which involves the use of the incremental creep theory and finite element method. Variable loading with load increase and relief at a constant temperature is considered as a stepwise process. The authors study a growth of deflections and stress relaxation in a intermediate-cylinder diaphragm of a steam turbine in various loading modes as well as special features of residual stress distribution in fixed blades.

2. Assessment of the crack resistance of multiple-seated lock joints of gas turbine blades.

Author

Shul’zhenko, N., Gontarovskii, P., and Melezhik, I.

Subjects
*TURBINE blades, *FINITE element method, *NUMERICAL analysis, *MATHEMATICAL analysis, *MECHANICS (Physics)
Abstract

We present results of assessing the crack resistance of three-seat lock joint of gas turbine blade under low-cycle fatigue and creep conditions of material in the presence of a hypothetical crack. The stress intensity factor is calculated by the finite element method. [ABSTRACT FROM AUTHOR]
