High Cycle Fatigue: A Mechanics of Materials Perspective part 1. The nomenclature used in this book may differ somewhat from what is considered standard or common usage. In such instances, this has been noted in a footnote. Additionally, units of measurement are not standard in many cases. While technical publications typically adhere to SI units these days, much of the work published by the engine manufacturers in the United States is presented using English units (pounds, inches, for example), because these are the units used as standard practice in that industry. The graphs and calculations came in those units and no attempt was made to convert. | I ELSEVIER HIGH CYCLE FATIGUE A MECHANICS OF MATERIALS PERSPECTIVE THEODORE NICHOLAS High Cycle Fatigue A Mechanics of Materials Perspective This page intentionally left .
