✦ Synopsis

Creep energy dissipation (CED) due to crack tip creep zone is determined under steady state conditions for centre cracked thin specimen of 1.25CrOSMo steel, with different widths and crack length to width ratios. The creep energy rate increases when the increment in crack length Au increases and the slope increases with increase in aspect ratio a/W and decreases with increase in width W.
