Multi-cracks Modeling in Reflective Cracking [PDF]

open access: yes, 2012
Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation. The stress concentration in the overlay

Threshold Crack Speed Controls Dynamical Fracture of Silicon Single Crystals [PDF]

open access: yes, 2007
Fracture experiments of single silicon crystals reveal that after the critical fracture load is reached, the crack speed jumps from zero to [approximate]2 km/sec, indicating that crack motion at lower speeds is forbidden.

Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]

open access: yes, 2010
In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

Elucidation of Mechanism of Brick Wall Frost Damage at JR Kitami Station

open access: yesJournal of MMIJ, 2016
In this study, we conducted a follow-up survey of brick cracking on a brick wall in the parking space of JR Kitami Station and installed temperature sensors on the surface of the brick wall in order to measure changes in the brick wall temperature during

Evolution of anodic stress corrosion cracking in a coated material [PDF]

open access: yes, 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
