Mechanical Analysis of Preventing Reflection Cracks Based on Stress Absorbing Layer
Advances in Civil Engineering, 2022 After asphalt concrete overlay, the reflection crack in the old pavement remains a great challenge. In order to overcome this problem, here, we report the effect of stress absorbing layer on the reflection crack.

Reflections in a cracked mirror [PDF]
British Journal of General Practice, 2009 How I hate the modern obsession with reflection. After every talk and lecture, at almost every trainers and appraisers meeting for the last few years and in everything associated with the medical learning industry, I am encouraged to reflect. To reflect on what I have learned and to shine that secondhand light on how my new knowledge will change the ...

Non-contact ultrasonic detection of angled surface defects [PDF]
, 2011 Non-destructive testing is an important technique, and improvements are constantly needed. Surface defects in metals are not necessarily confined to orientations normal to the sample surface; however, much of the previous work investigating the ...

Signal enhancement of the in-plane and out-of-plane Rayleigh wave components [PDF]
, 2005 Several groups have reported an enhancement of the ultrasonic Rayleigh wave when scanning close to a surface-breaking defect in a metal sample. This enhancement may be explained as an interference effect where the waves passing directly between source ...

Sensors, 2016 This paper presents a novel framework for probabilistic crack size quantification using fiber Bragg grating (FBG) sensors. The key idea is to use a high-order extended finite element method (XFEM) together with a transfer (T)-matrix method to analyze the

Frictional sliding without geometrical reflection symmetry [PDF]
, 2016 The dynamics of frictional interfaces play an important role in many physical systems spanning a broad range of scales. It is well-known that frictional interfaces separating two dissimilar materials couple interfacial slip and normal stress variations ...

The Reflective Cracking in Flexible Pavements [PDF]
Romanian Journal of Transport Infrastructure, 2013 Abstract 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.

Observation of nano-indent induced strain fields and dislocation generation in silicon wafers using micro-raman spectroscopy and white beam x-ray topography [PDF]
, 2010 In the semiconductor manufacturing industry, wafer handling introduces micro-cracks at the wafer edge. During heat treatment these can produce larger, long-range cracks in the wafer which can cause wafer breakage during manufacture.
