"penetration defect" is a correct and usable phrase in written English.
It is typically used in technical or scientific writing to describe a flaw or weakness in the ability of a substance or material to penetrate or pass through another substance or material. Example: The researchers discovered a penetration defect in the coating of the metal, causing it to corrode faster than expected.
Figure 14 2D intensity profiles of the line 9 in the ROI of the lack of penetration defect.
This further reduces appressorial turgor pressure, which eventually leads to a penetration defect.
A decrease in proliferation or an increase in apoptosis could result in the ductal penetration defect associated with ErbB3-/ transplants.
The length of the ErbB3+ outgrowths and the severity of the ErbB3-/ penetration defect varied at 4 weeks.
In addition to the ductal penetration defect, there was an increase in the number of branchpoints in the ErbB3-/ outgrowths in comparison to the ErbB+ outgrowths.
This ductal penetration defect persisted in adult nonparous ErbB3-/ glands (two glands; Figures 1f and 2e), and was not rescued by the influence of hormones during pregnancy or lactation.
Deep penetration, defect-free, and oxygen contamination free welds were achieved under an optimum combination of laser parameters including focal length of lens, pulse energy, pulse repetition rate, beam travel speed, and an innovative shielding gas arrangement.
Figures 6a1, a2 and 7a1, a2 represent four radiographic images of weld with internal undercut, external undercut, lack of fusion, and lack of penetration defects, respectively.
Some simulation results of the PMAD applied to images of weld are given in Figures 6 and 7. Indeed Figures 6a1, a2 and 7a1, a2 represent four radiographic images of weld with internal undercut, external undercut, lack of fusion, and lack of penetration defects, respectively.
The severity of the ErbB3-/ ductal penetration defects varied.
Using a high-power fibre laser, Katayama et al. (2009) investigated penetration and defect formation in several aluminium alloys.
