Calculation procedure of a fatique point for strengthened cylindrical specimen with pressure concentrators at temperature endurances in the creep conditions

Calculation procedure of influence of temperature endurances on an increment of a fatique point for strengthened cylindrical specimen with pressure concentrators is proposed. In order to illustrate the method on modelling examples it is demonstrated that residual pressure relaxation leads to decrease in an increment of a fatique point of strengthened specimen in relation to non strengthened specimen of 20–40 % due to creep at temperature endurances Results of calculations are quoted.
