STRESS INTENSITY FACTOR (KI) FOR A STEAM PIPE
SUBJECTED ONLY TO THERMAL SHOCK (ΔθS)
The temperature of a steam pipe is variable because of the steam
pressure variation inside of it. If the steam temperature variation takes place
during a short time, the steam is subjected under a thermal shock. The effect of
the thermal shock is superimposed on the effect of the mechanical load, going
to an additional load on the pipe. The thermal shocks are dangerous for the
strength elements.
In the paper is presented the variation of stress intensity factor of a
steam pipe subjected only to thermal shock.
