Based on detailed FE limit analyses, the present paper provides tractable approximations for plastic limit<br/>
pressure solutions for axial through-wall cracked pipe; axial (inner) surface cracked pipe; circumferential<br/>
through-wall cracked pipe; and circumferential (inner) surface cracked pipe. Comparisons with existing<br/>
analytical and empirical solutions show a large discrepancy in circumferential short through-wall cracks and<br/>
in surface cracks (both axial and circumferential). Being based on detailed 3-D FE limit analysis, the present<br/>
solutions are believed to be the most accurate, and thus to be valuable information not only for plastic<br/>
collapse analysis of pressurised piping but also for estimating non-linear fracture mechanics parameters based<br/>
on the reference stress approach.
