Question

What is meant by stress concentration factor? How does this differ from the stress intensity factor?

Answer 1

The stress concentration factor in the examined structure can be used to compensate for the existence of so-called stress raisers.

Step-by-step explanation:

The stress concentration factor in the examined structure can be used to compensate for the existence of so-called stress raisers. These are the positions where tension, such as notches, holes or other structural discontinuities, are focused. It can be identified cracks but is mostly used in basic material problem mechanics as well as fatigue assessment.

Strain strength factor is directly associated with the dynamics of fracture and is used in this field of strong mechanics. For a given crack it can be measured and then compared to the critical value (critical pressure strength factor) beyond which the crack propagates.

Answer 2

Explained

Step-by-step explanation:

The stress raisers in the analysed structure such as notches, wears, and geometric discontinuity account for the stress concentration factor. It is also represented by the letter K.

Whereas stress intensity factor is directly related to fracture mechanics. It is the inherent property of the material that is tested and defined for cracks and flows. It is often used for fatigue calculation of metals and for strength determination of brittle materials like ceramics and glasses.
