The phrase "a decrease in modulus for" is correct and usable in written English.
It can be used in contexts related to materials science, engineering, or physics when discussing changes in the modulus of elasticity or similar properties.
Example: "The study revealed a decrease in modulus for the composite material after prolonged exposure to moisture."
Alternatives: "a reduction in modulus for" or "a decline in modulus for".
The storage modulus value of the scaffolds increased from 441 MPa for neat PLGA to 724 MPa for 5% nano-HA; however, further increasing the concentration leads to a decrease in storage modulus, to 371 MPa for 20% nano-HA.
Only a load in the center was used for the example, but the main result (decrease in stress with a decrease in concrete modulus) would be obtained for other load locations (corner or edge).
It is also found that the high dislocation density in lath martensite accounts for a decrease in shear modulus by about 5% compared to the ferritic counterpart.
In Section D, fibroblast response to a decrease in substrate modulus was highlighted.
Following five days of incubation, a statistical difference in elastic modulus was not always observed at 50% strain in hydrogels exhibiting a shift in the LVE limit, due to a decrease in elastic modulus above the LVE limit.
The shift indicates that incubation induced changes in hydrogel structure is maintained over time and is not lost with a decrease in elastic modulus.
Furthermore, addition of 0.25% chitosan and 0.01% genipin to 0.5% alginate hydrogels prevents a decrease in elastic modulus at 1% strain that is observed in 0.5% alginate hydrogels.
A considerable decrease in modulus was observed for modified poly(GMA-co-MMA) and poly(GMA-co-EMA) and increase in modulus observes for modified poly(GMA-co-MA) and poly(GMA-co-BA) with respect to modified copolymers of GMA.
In all materials, high frequency applied cyclic loading during in situ degradation resulted in catastrophic fracture of the material prior to an appreciable decrease in modulus.
The typical features of the Payne effect, i.e., a decrease in the storage modulus with increasing strain, can be seen for all the studied composite samples.
