WebThe drilled hole, with its relatively large size, serves to increase the effective crack tip radius and thus reduce the stress concentration. Another method used to decrease the stress concentration is by adding a fillet to internal corners. This reduces the stress concentration and results in smoother flow of stress streamlines. A crack growth equation is used for calculating the size of a fatigue crack growing from cyclic loads. The growth of fatigue cracks can result in catastrophic failure, particularly in the case of aircraft. A crack growth equation can be used to ensure safety, both in the design phase and during operation, by predicting the size of cracks. In critical structure, loads can be recorded and u… how to download ration card online delhiWebExample - Flow Coefficient Liquid.
