High-Density Distributed Crack Tip Sensing System Using Dense Ultra-Short FBG Sensors
Sensors, 2019 Crack generation starts at the crack tip, which bears the highest stress concentration. Under further stress, the crack propagates and leads to severe structural damage.

Reflective cracking behavior for traffic and temperature effects [PDF]
, 2008 This paper presents a study on the influence of the effects of temperature variations, in comparison with traffic effects, on the reflective cracking overlay behavior. It is intended to contribute to the improvement of the pavement overlay design methods which consider reflective cracking as one among distress criteria.

Fatigue fracture surface analysis in C45 steel specimens using X-Ray fractography [PDF]
, 1991 X-Ray fractography is a useful technique to analyse the mechanisms operating in fracture and involves an examination of the fracture surface. In the present investigation, this technique has been employed to study the fatigue fracture behaviour of a ...

Neural Networks Modeling of Stress Growth in Asphalt Overlays due to Load and Thermal Effects during Reflection Cracking [PDF]
, 2011 Although several techniques have been introduced to reduce reflective cracking, one of the primary forms of distress in hot-mix asphalt (HMA) overlays of flexible and rigid pavements, the underlying mechanism and causes of reflective cracking are not yet
