  fracture
Fracture is a common defect in sheet metal forming and it is essentially caused by tensile instability.
      
Fracture and spalling traces as well as an overlapping structure of multilayer surface films can be easily found on the surface film.
      
The fracture surface of the pore is funnel-shaped.
      
The results show that at room temperature and R = 0.1 conditions, the characteristics of fatigue fracture could be observed.
      
Under those conditions, the fatigue strength and the fracture toughness of a 2124-T851 thick plate is 243 MPa and 29.64 MPa · m1/2, respectively.

  fissure
All these vary with many factors such as fluid pressure, oil saturation, fissure configuration and wettability, and these factors affect each other.
      
Speed of flow relates to the angle and width of the fissure.
      
Speed of flow in the wide fissure that has an acute angle with the pressure gradient is faster than that in a narrow fissure with a high angle with the pressure gradient.
      
Cellular composition of the peripheral region of the eye in amphibians and mammals as well as embryonic fissure in amphibians was studied.

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.

  crevice
On the Effectiveness of an Inhibitor in Crevice Corrosion Protection (Theoretical Assessments)
      
Because of the diffusion limitations, the dynamics of inhibiting crevice corrosion is shown to depend on the width and extension of the crevice.
      
In particular, the time of reaching the maximum adsorption of the inhibitor grows with a decrease in the width and an increase in the length of the crevice.
      
The possibilities offered by various setups for the investigation of crevice corrosion are considered.
      
In 2000-2002 bat droppings were collected under the emerging crevice of a nursery colony of Pipistrellus pygmaeus.
