Fatigue — where it appears
2 essays name this object, across one field. What follows is each of them, and the objects they name alongside it.
The hole that multiplies the stress by three
The stress at the side of a hole is three times the applied stress whatever the hole's size, and at the top and bottom of the same hole it is minus one times it — compression in a plate that nothing is pushing.
The load that never came near failing anything
A detail survives sixty-eight million cycles at a stress range that another detail in the same steel survives two hundred and seventy thousand of. The two lie a factor of two hundred and fifty apart, and the material is not on the plot anywhere.
