Evaluation of combined hardening model in ratcheting behavior of pressurized piping elbows subjected to in-plane moments
In this paper the ratcheting behavior of carbon steel(ASTM A106B) and stainless steel(304L) elbows is studied under steady internal pressure and in-plane external moments at frequencies typical of seismic excitations. The finite element analysis with the nonlinear isotropic/kinematic (combined) hardening model has been used to evaluate ratcheting behavior of the elbows. Material parameters have...
متن کاملRatcheting-Fatigue Failure of Pressurized Elbows made of Carbon Steel
Ratcheting-fatigue investigations have been carried out to understand the ratcheting-fatigue failure of carbon manganese steel (conforming to ASME specification of SA-333 Gr.6). Experiments have been conducted on pressurized pipe-elbow assembly subjected to reversible cyclic bending, to assess the failure mechanics owing to ratcheting-fatigue synergy. These studies are required to evaluate the ...
متن کاملProcess Piping: Polymers Versus Stainless Steel
choice for pharmaceutical industry process systems. Its high mechanical strength and low coefficient of thermal expansion allow components to be sterilised or sanitised using various mediums and at high temperatures. Concerns about stainless steel systems – such as rouging in high purity water, metallic ion contamination and inner surface finishes – which require post-installation maintenance a...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
