The phrase "at a mean load" is correct and usable in written English.
It can be used in contexts related to engineering, statistics, or performance analysis where average load conditions are being discussed.
Example: "The system operates efficiently at a mean load, ensuring optimal performance during peak hours."
Alternatives: "under average load" or "at average capacity".
Intact atrophied synthetic mandibles broke at a mean (SD) load of 729.48 (59.94) N (control group).
Fatigue extrusions imply a dynamic form of crack closure that could develop immediately at the crack tip even for fatigue at high mean load.
At six weeks the mean load at failure for the direct bone repair (plate fixation) group was 31.0 N (sd 8.5) and the stress at failure was 24.7 N/mm (sd 6.2).
In this study, a significant increase in mean load at 2-mm gap formation with barbed sutures was exhibited, independently of suture material, compared with a traditional Kessler suture.
The two-sample Student t-test demonstrated a significant increase in mean load at 2-mm gap formation with barbed sutures, independently from suture material, when compared to a traditional Kessler suture.
In order to develop an appropriate fatigue damage parameter of the rubber material, load-controlled fatigue tests were conducted using three-dimensional dumbbell specimens at different levels of mean load.
For oblique loads, the locking construct failed at higher mean loads but the difference of means was not statistically significant (167.7 ± 14.9 N compared to 154.2 ± 9.4 N, P = 0.052).

At six weeks in the external fixation group the mean load and stress at failure for the healing tibial osteotomies was 25.9 N (sd 10.6) and 21.8 N/mm (sd 3.0), respectively, and 166.4 N (sd 50.8) and 160.1 N/mm (sd 50.8) for the intact contralateral tibiae, respectively.
