Root Cause Failure Analysis - Understanding Mechanical Failures
" on the right causes the crack to grow in a non-uniform manner. In general, when the divider of the instantaneous zone does not point to the origin, it shows there was a rotating bending involved in the failure cause. Figure 7 HOW HEAVILY WAS IT LOADED? Fatigue failures almost always start on the outside
Considerations for Step Motors in Space Applications
are typically due to weight and size restrictions placed upon the designer. However even a slight misalignment between the motor and a rigidly coupled load will bend the shaft as it is rotating. This bending fatigue is aggravated by snap ring grooves or machined cuts, and brittleness at cold temperature
