  crack
The relationship between medial crack length and normal loading was also investigated when specimens were indented by symmetrical wedges with interior angles of 30°-120°.
      
Crack fault quantitative diagnosis based on finite element of B-spline wavelet on the interval
      
The model-based forward and inverse problems in the diagnosis of structural crack faults were studied.
      
The forward problem is to solve the natural frequencies through a cracked structural model and the inverse problem is to quantitatively determine the crack parameters using the experimental testing frequencies.
      
Then, the one-dimensional crack element of B-spline wavelet on the interval (BSWI) was built to solve the forward problem.

  cracks
Plane elastic problems of different media with cracks on the interface
      
The equilibrium problem for the infinite elastic plane consisting of two different media with many cracks on the interface is discussed.
      
Low pit aspiration ratio and cracks of some bordered pits are the main reasons for the increase in liquid penetration after RFVD treatment.
      
Initiation and propagation laws of the glass cracks in specimens subjected to normal loading under the action of symmetric wedge
      
To improve the machining precision of part surfaces and to facilitate tool design and cutting parameter selection, the initiation and propagation laws of glass cracks in specimens subjected to normal loading by symmetric wedges were investigated.

  crackle
Four different styles of brecciation can be distinguished at the Pering deposit: (1) pyritic rock matrix breccia; (2) chemical wear breccia; (3) mosaic breccia; and (4) crackle breccia.
      
The latter is very uniform across the entire deposit and typically cements mosaic and crackle breccia, but also fills remaining open space within chemical wear brecciated portions of the deposit.
      
An automatic method for crackle detection is developed, based on analysing the spectral stationarity of the lung sound.
      
Lung sound crackle analysis using generalised time-frequency representations
      
At low gas flows, no gel-induced crackle sound was generated within the data capture window when the most viscous gel was examined.

  the crack
The forward problem is to solve the natural frequencies through a cracked structural model and the inverse problem is to quantitatively determine the crack parameters using the experimental testing frequencies.
      
By analyzing the bifurcation plot, Poincare section plots and amplitude spectra, we found that the crack greatly influences the dynamic characteristics of the rotor-bearing system.
      
The effect of hydrogen on the susceptibility is more obvious in the low stress region due to the longer fracture time, which resulted in a longer time for more hydrogen to diffuse toward the crack tip.
      
The results showed that an interaction between stress and hydrogen at the crack tip could increase the anodic dissolution rate remarkably.
      
Utilizing the obtained load against crack opening displacement curve, the value of GI-bridging at any crack extension as well as the change of GI-bridging with the crack extension is examined.
