The phrase "a weak layer of" is correct and usable in written English.
It can be used to describe a thin or fragile stratum of material or substance in various contexts, such as geology, construction, or even metaphorically in discussions about social structures.
Example: "The geologist noted that there was a weak layer of sedimentary rock beneath the surface, which could lead to instability during the excavation."
Alternatives: "a fragile layer of" or "a thin layer of".
The biggest cause of avalanches is a weak layer of snow on a slope covered by solid layers, Dr. Adams said.
Slides often result when there is a weak layer of snow on a slope covered by solid layers, and scientists say they are hard to predict.
A weak layer of tissue called the abscission layer develops at the base of each leaf stalk, and at this point the stalk breaks and the leaf is shed.
Corrosion leads to a reduction of the reinforcing bar diameter, the formation of a weak layer of corrosion products around the bar and expansive forces on the surrounding concrete (that can lead to cracking).
The posterior fornix is more vulnerable to injury as a result of a weaker layer of endopelvic fascia [ 4, 8- 11].
The difference in the composition of magmatic rocks is attributed to different extents of melt-peridotite reaction at the slab-mantle interface, where there is a jelly-sandwich structure in which a weak layer composed of metamorphic, anatectic and metasomatic rocks (the jelly) is sandwiched between the overlying mantle wedge and the underlying subducted crustal slab (Zheng et al. 2013).
THE ARTS, PAGE E1 Engineers Point to Flaws In Design of Floodwalls In the early 1980's the Army Corps of Engineers drove the anchors for a New Orleans levee wall no deeper than 17 feet below sea level, despite a potentially weak layer of peat soil 15 feet deep.
This study presents a more rigorous "quantified loaded column test" (QLCT) methodology designed to produce a continuous, in-situ measurement, at a sloping site, of the shear strength of a weak layer.
Dry snow avalanches release by the failure of a weak layer.
This adhesive failure must be due to the weak layer of demineralized dentin in the restored dentin.
Previous energy-based models predict that multiple "tunnel" cracks in the weak layers of the shell account for a factor of 20 of this increase in fracture energy.
