Publication: Relation between rupture time and steady state rate integral
Abstract
Experimental investigations have been carried out on the creep crack growth behaviour in types 316, 308 Cb and 304 L stainless steels under a plane stress condition. The crack initiation starts at the second half of the steady state deformation of the material in all the cases. It has been observed that the rupture time (tr) bears an inverse relation to the steady state energy rate line integral, C*, in the form of C*str = R where Cs* is that value of the energy rate line integral in the steady state condition and R is a constant. © 1990.
