The phrase "drop in strength" is correct and can be used in written English.
It means a decrease or decline in strength or power. Example: "The athlete's performance suffered due to a drop in strength caused by his recent injury."
The strength and modulus of samples cut along the growth direction were 1.8× and 4.9× higher than those cut in the 90° direction, with a smooth drop in strength observed as the cutting direction increased from 0° to 90°.
The use of hollow trusses increases the resistance to buckling offsetting the usually rapid drop in strength as the relative density decreases in cellular systems where truss buckling controls failure.
When polypropylene fibre is used, it usually yields a large drop in strength immediately after the first crack, as well as a lower post-peak response, owing to its high flexibility and low stiffness.
While UHSCs were not significantly affected by increasing gypsum content of sand, the Portland cement mortars deteriorated as seen by a drop in strength, a significant swelling, and the presence of expansive ettringite.
It may be expected from these results that PP of high fluidity can be produced without a drop in strength if the weight-average molecular weight approaches the number-average molecular weight under the retention of the number-average molecular weight.
For series B ternary concretes, the porosity is more significant with coarse aggregates, which explains the drop in strength.
MIAMI — It may have dropped in strength, but Hurricane Florence is in every other way behaving as expected: a huge, slow-moving, very rainy storm that is already pushing sea waters many feet above normal onto the beaches of North Carolina.
After quickly dropping in strength to a Category 2 hurricane, Fausto weakened at nearly the same rate as it had intensified.
For freeze thaw testing, after 150 cycles, the LMM control samples experienced a drastic drop in compressive strength; however, it gained part of the lost strength (about 50%) after 300 cycles.
The splitting tensile and flexural strength of BFRC and GFRC were improved with increasing fiber content whereas a slight drop in flexural strength was observed for high volume of fiber content.
The full-graded large samples had compressive strength of 10% higher than that of wet-screened small samples, with however a considerable drop in tensile strength.
