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.

A Dynamic Atomistic-Continuum Method for the Simulation of Crystalline Materials

, 2001
We present a coupled atomistic-continuum method for the modeling of defects and interface dynamics of crystalline materials. The method uses atomistic models such as molecular dynamics near defects and interfaces, and continuum models away from defects ...

Study on Composition Design and Performance Characteristics of Warm-Mixed Rubber–Asphalt Mixture for Cold-Region Stress Absorption Layers

Buildings
Reflection cracks significantly compromise the service life of half-rigid asphalt pavements in cold regions. This study introduces SAKIII warm-mixed rubber–asphalt mixture (SAKIII WMRA Mix) as a stress absorption layer to address this issue.

The Analysis of FBG Central Wavelength Variation with Crack Propagation Based on a Self-Adaptive Multi-Peak Detection Algorithm

Sensors, 2019
We propose a peak seeking algorithm to extract the damage characteristic-variation of central wavelength to monitor the crack damage status in aluminum alloy plates using surface bonded fiber Bragg grating (FBG) sensors.

Continuous monitoring of an intentionally-manufactured crack using an automated welding and in-process inspection system

Materials & Design, 2020
Automated weld deposition coupled with the real-time robotic Non-Destructive Evaluation (NDE) is used in this paper. For performance verification of the in-process inspection system, an intentionally embedded defect, a tungsten rod, is introduced into ...

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 ...
