"design strength" is a correct and usable phrase in written English.
You can use it to refer to the strength of a structure or product that has been designed or engineered for a specific purpose. For example, "The design strength of the bridge was tested before it could be opened to the public."
Concrete cures slowly; the design strength is usually reached 28 days after initial setting.
In addition, Airbus said, using the rudder in alternating directions "can lead to structural loads that exceed the design strength of the fin and other associated airframe components".
"We would double the design strength, just to give it a factor of safety," Mr. Dooley said, referring to practices in the United States.
The bonding gel structure forms slowly, and the design strength is usually taken as that occurring 28 days after the initial setting of the mix.
Wrong acid design (strength, volume, etc).
The design strength of 50 and 55 MPa was achieved.
Additionally, the reduction factor for the design strength by the fatigue effect should be considered in estimation of design strength.
Except for the B-2 specimen with a significantly lower strength value in the negative direction, the ratios were 1.46 1.64 times higher than the design strength, indicating that the average is about 1.5 times the design strength.
