At the opening of the bottle, there is a lip that creates a stress concentration.
Another way to understand this phenomenon is by comparing it to the stress concentration at the point of failure mentioned earlier.
They are also used to add a radius between perpendicular faces to reduce stress concentrations.
The effect of stress concentration and manufacturing error are neglected.
Such stress concentrations are a primary cause of failure in poorly designed splines.
Whatever the scale, the practical importance of stress concentrations is enormous.
It would however produce a stress concentration of 201 among the molecules near the crack tip.
However, over time, as the glass expands and contracts, stress concentrations can develop around the nick that break the entire unit.
High stresses at the surface may be compounded by stress concentrations such as rough spots.
The implants can also cause stress concentrations, as a result of the material difference between the bone and the plate.
