Crack width and crack spacing in reinforced and prestressed concrete elements: Data description and acquisition. [PDF]
Existing databases containing measurements of crack width and spacing are usually limited in size and based on isolated experimental studies. These databases are used to develop new formulas to describe crack patterns in concrete structures. A database obtained from multiple sources of experimental programmes is required to quantify the accuracy of ...

Investigation of transverse crack spacing in an asphalt pavement with a semi-rigid base [PDF]
Transverse cracking is a serious problem for semi-rigid base asphalt pavement. The shrinkage of the base course and the surface course, as well as reflective cracks, are key factors for transverse cracking in asphalt pavement.

Failure in plain and reinforced concrete—an analysis of crack width and crack spacing [PDF]
The proper prediction of crack widths in plain concrete and the spacing of primary cracks in reinforced concrete are the subject of this paper. Attention is focused on the influence of the crack concept. A comparison has been made between the standard crack model, the crack model with the fracture energy as a separate parameter, the rate-dependent ...

The effect of different borehole spacing and detonation time difference on crack propagation in double-hole shaped charge blasting. [PDF]
Achieving precise through-crack between shaped charge blasting holes depends critically on the design parameters of the blasting operation. This study investigated the influence of borehole spacing and detonation time difference on crack propagation in ...

Crack growth resistance in nuclear graphite [PDF]
R-curve behaviour is often used for evaluating crack growth resistance in quasibrittle materials but few studies have focused on polycrystalline graphite. In this study, R-curve behaviour in three commercial grade nuclear graphites, of varying structure

In-situ observation of micro-cracking in a SiC/BN/SiC ceramic matrix composite under tension
Crack spacing and crack opening displacement values are critical for CMC damage and oxidation modeling. A tensile stage used with light and scanning electron microscopy (SEM) was utilized to evaluate micro-cracking under load in SiC/BN/SiC ceramic matrix
