Ratcheting-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 کاملFatigue Failure of Structural Steel – Analysis Using Fracture Mechanics
Fatigue is the major threat in service of steel structure subjected to fluctuating loads. With the additional effect of corrosion and presence of weld joints the fatigue failure may become more critical in structural steel. One of the apt examples of such structural is the sailing ship. This is experiencing a constant stress due to floating and a pulsating bending load due to the waves. This pa...
متن کاملImpact Fatigue Behaviour of Flapper Valve Steel
The purpose of this study is to discuss the impact fatigue failure mechanism of a suction valve that involves the fracture with fragments torn off from the edge or surface. The shape and dimensions of the test specimen and stopper were made the same as those of the suction valve and stopper in an actual compressor. The specimen was operated by short-duration compressed air pulses, and struck ag...
متن کاملFatigue Assessment of Complex Welded Steel Structures
To improve the usage of material in fatigue loaded complex welded structures a better calculation method (based on FEA) is needed than what is available on the market and an improved management of weld quality. Improved FE-procedures are directly applicable to design of generic structural components within virtually all industries using CAD and FEtools, irrespective of industrial sector. More a...
متن کاملFatigue Failure and Damage Analysis of an Anti-roll Bar Subjected to Fatigue Experiments
The available fatigue theories have been examined using simple specimens subjected to bending or tension-compression loads. Therefore, the stress fields have been generally one or two dimensional. Anti-roll bar is a component belongs to the suspension system of the vehicles. In spite of having simple circular section, due to the having several curvatures, this component experiences a three-dime...
