In discussion of the welded joints from fracture mechanics point of
view, it is assumed that the welded joint is pre-cracked and that therefore fatigue life
of the pre-cracked structure is determined by the period of crack growth under
variable loading. Experimental data obtained by testing provide a substantial
foundation for better understanding and explanation of the phenomenon of fatigue of
a material. Low-cycle fatigue (LCF) occurs during charging and discharging of the
reactors, pressure vessels and pipelines; it can be accelerated by additional negative
effect of temperature variation and aggressive effect of vessel contents during
exploitation of the equipment in processing industry.
In present paper, the results of measurement of J-integral of weld metal made of
low-alloy high-strength steel, used for manufacture of the pressure vessels in the
process of powder welding, at LCF have been presented.
