Surface Crack Growth in Metallic Pipes Reinforced with Composite Repair System

Surface cracks are serious threats to the structural integrity of offshore metallic pipes. This dissertation proposes a protocol of composite reinforcement on surface cracked metallic pipes subjected to cyclic loads, aiming to decrease the crack growth rate and prolong the residual fatigue life. The main objective of this dissertation is to...

Surface crack growth in offshore metallic pipes under cyclic loads: A literature review

The surface crack, also known as the partly through-thickness crack, is a serious threat to the structural integrity of offshore metallic pipes. In this paper, we review the research progress in regard to surface crack growth in metallic pipes subjected to cyclic loads from the fracture mechanics perspective. The purpose is to provide state-of...

Numerical investigation of residual ultimate strength of dented metallic pipes subjected to pure bending

A dent is one of the main structural damages that may affect ultimate strength. In this paper, the residual ultimate strength of dented metallic pipes subjected to a bending moment is quantitatively investigated. The numerical model is developed accounting for the variation of the dent length (l_d), dent depth (d_d), dent...

Inductive Power Transfer through Metal Object

The principle of Inductive Power Transfer (IPT) is very old but it is rarely used for transferring power from source to load via a medium. This is because normally the medium restricts the power transfer due to losses or the shielding effects. However, for low energy applications, an acceptable amount of power could be transferred from the...
