Abstract: Hollow sections are generally either circular-to-circular (CCHS) or rectangular-to-rectangular (RRHS). Structures with circular braces and rectangular chords (CRHS) may have advantages in certain applications, combining a ...

Abstract: A procedure is developed to evaluate and rank tribomaterials based on wear parameters using a vectorial approach. The method known as the Hasse Diagram approach allows one to graphically compare ...

Abstract: System structure is important for analyzing wear of a system. In this paper, this aspect is considered at the component level and is modeled using digraph and matrix methods. Contributing wear ...

Abstract: The paper presents a methodology to analyze failure cause of a system using structural approach based on digraph and matrix method. Failure causality digraph models the failure cause considering ...

Abstract: 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 ...

Abstract: Steel jacket platforms are widely used for production and processing of oil from offshore fields. Tubular joints of these structures are susceptible to fatigue or corrosion fatigue cracking due ...

Abstract: Welded tubular structures are widely used for offshore platforms. In India, there are more than 120 offshore platforms in the Bombay High region, all of which are jacket‐type structures consisting of welded tubular members. ...

Abstract: The determination of depth profile of vertical fatigue cracks generated in thick cruciform samples using an ultrasonic phased array is investigated in this paper. The cracks were formed by ...

Abstract: “Ratcheting” is a phenomenon which leads to reduction in fatigue life of a structural component by loss of ductility due to cycle by cycle accumulation of plastic strain. Ratcheting occurs in ...
