May/June 1999 Inspectioneering JournalBy Del Underwood at Det Norske Veritas
In two previous issues we discussed the important difference between steady and cyclic loading, and why loose bolts fail while tight ones do not. This issue will offer two suggestions for reducing the tendency for bolts to become loose.

January/February 1999 Inspectioneering JournalBy Del Underwood at Det Norske Veritas
In the previous issue, we dealt with the fact that bolts can withstand significantly less cyclic loading then steady loading. We are now looking at the mechanics of why bolts fail if flanges are allowed to separate during operation.
