"useful damage" is a grammatically correct phrase and can be used in written English
It can typically be used to describe a situation where some amount of damage or harm is acceptable or beneficial in achieving a certain goal or outcome. Example: The demolition crew strategically caused some useful damage to the old building in order to make room for a new shopping complex.
It is therefore concluded that AE energy provides a valid and useful damage parameter and effective failure criteria for fatigue life prediction, accounting for the material's current damage state, its response to variations in loading and effective intermediate failures.
The system automatically divides the belt into sections and counts the defects and their surface area, thus offering useful damage measurement units such as damage density or damage surface area per 1 running meter of belt.
The latter makes our approach particularly useful in damage assessment applications.
Overall, the experimental outcome was useful for damage tolerance analyses since, in real structures with realistic loading scenarios, similar failure locus was expected.
Bulging factor expressions developed and available in the literature so far, are useful for damage tolerance design and characterization of internally pressurized cracked isotropic shell structures.
The results and insights developed in the present study will be useful for damage tolerant design of steel plated structures with local denting.
Simulation results indicate that the system detects attacks with reasonable accuracy, and is useful for damage control in both QoS-enabled and best effort network domains.
It is observed that the experimental results are in good agreement with the computational results and the proposed simulation model is very useful for damage assessment.
The results and insights developed from the present study will be very useful for damage tolerant design of steel plated structures with local denting.
The insights developed from the present study will be very useful for damage tolerant design of plated structures with pit corrosion wastage.
Two statistical methods based on (i) moving principal component analysis and (ii) robust regression analysis are demonstrated to be useful for damage detection during continuous static monitoring of civil structures.
