Evolution of anodic stress corrosion cracking in a coated material [PDF]
, 2010 In the present paper, we investigate the influence of corrosion driving forces and interfacial toughness for a coated material subjected to mechanical loading. If the protective coating is cracked, the substrate material may become exposed to a corrosive

Node-to-segment and node-to-surface interface finite elements for fracture mechanics [PDF]
, 2016 The topologies of existing interface elements used to discretize cohesive cracks are such that they can be used to compute the relative displacements (displacement discontinuities) of two opposing segments (in 2D) or of two opposing facets (in 3D ...

Subsonic Interface Crack with Crack Face Contact [PDF]
Advanced Materials Research, 2008 A steady-state subsonic interface crack propagating between an elastic solid and a rigid substrate with crack face contact is studied. Two cases with respective to the contact length are considered, i.e., semi-infinite and finite crack face contact. Different from a stationary or an open subsonic interface crack, stress singularity at the crack tip in ...

Interface damage modeled by spring boundary conditions for in-plane elastic waves [PDF]
, 2011 In-plane elastic wave propagation in the presence of a damaged interface is investigated. The damage is modeled as a distribution of small cracks and this is transformed into a spring boundary condition.

Interface Damages of Electrical Insulation in Factory Joints of High Voltage Submarine Cables
Energies, 2020 As a key accessory of high-voltage (HV) insulated submarine cable, the factory joints of the cross-linked polyethylene (XLPE) represent an unpredictable uncertainty in cable-connecting fabrications by means of the extruded molding joint (EMJ) technique ...

Engineering Analysis with Boundary Elements, 1989 Abstract This paper deals with the determination of stress intensity factors for plane cracks which are at or near interfaces. The interface may be straight or curved and be a free surface or between two elastically dissimilar materials. Any bulk stress field may be catered for as may partially closed cracks.

Effects of pre-cracks on both initiation and propagation of re-bar corrosion in pure carbon dioxide
EPJ Web of Conferences, 2013 This paper deals with effects of pre-cracks on both initiation and propagation of reinforcement steel corrosion due to carbonation. The ring shaped mortar samples with 8 mm steel bar inside were cracked with different crack widths ranging from 12 ...
