Fatigue cracks are found to appear in welded steel tubular joints of offshore structures during their service life necessitating costly repairs and maintenance. Two unstiffened and seven internally ring stiffened steel tubular joints were tested unde

Earthquake load, which is cyclic in nature and of short duration, is the main design basis accident load for designing the primary heat transport (PHT) piping components of Nuclear Power Plants. Adequate protection of piping components from the effec

In order to evaluate the structural integrity of power plants, it is required to know the load carrying capacity of a piping system. J-integral based elastic-plastic fracture mechanics (EPFM) has become a useful analytical technique for dealing with

Studies have been carried out on carbon steel pipes to demonstrate the leak before break design criterion and validate the analytical procedures. Fatigue crack initiation, fatigue crack growth rate and fracture resistance behaviour of the pipes have

The use of internal ring stiffeners in offshore steel jacket platforms is a subject of controversy because of their peculiar failure pattern, observed in several tests in the early 1980s. It is estimated that at least 2,000 internally ring-stiffened
