Back in 2010, when Netflix pivoted its focus to streaming content, it was an innovative and unique platform for watching shows and movies. One of the main reasons Netflix became so popular was its cutting-edge newness.This paper investigated how the stop drilling procedure improved the crack initiation life and the total fatigue life in specimens of 6061-T651 aluminium alloy and AISI 304 stainless steel. The crack initiation life was the number of fatigue cycles initiating a 0.2 mm crack at a stophole edge. The larger the stophole diameter, the longer the crack initiation and total fatigue lives.

The objective of drilling a hole is to reduce the stress concentration at the crack tip. This repair method is called a stop drilling procedure.In the present study, the stop-hole method was investigated with creating a noncircular hole. The aim of the present work was to obtain an optimum stop hole shape that gives maximum fatigue crack initiation life by using finite element program. It was found that the fatigue life obtained by using the optimum hole shape ranges from 2 to 9 times ...

Fatigue cracking is a major concern for many aging steel bridges in the United States. A common form of crack remediation is the drilling of crack-arrest holes, increasing the crack tip radius and thus reducing the applied stress intensity. However, the majority of cracking that occurs in bridge structures is caused by distortion-induced fatigue.I am no specialist but i would pierce a 1/4 inche diameter hole at each end of the crack.
