In summary, the conversation involves a person urgently needing a chart of theoretical stress-concentration factors for a specific case involving two thin plates connected parallel to each other with one shorter than the other. They also mention needing information on the case of a clamped wide and thin beam with a bending moment. The person asks for book references and is directed to Peterson's Stress Concentration Factors (ISBN 0-471-53849-3). They state that they will check another library for the book.

urgent: stress-concentration factors

Hey people,

I urgently need a chart of theoretical stress-concentration factors for the following general case: a part made from two thin plates of equal weidth connected parallel to each other with one shorter than the other. I need the theoretical stress-concentration factors for the connection corners between the plates (as a function of fillet radius) - when there's a bending moment acting on the major surface of one of the plates. Maybe even the case of a clamped wide and thin beam with a bending moment will do.

Book references, if you know there's such a case there (because I already tried to find it in a library) will help to.

Thanks a lot :smile:

Can you get a hold of Peterson's Stress Concentration Factors (ISBN 0-471-53849-3)?

One library closed, I'm on my way to the next. It's probably there. Thanks.
 

Related to : stress-concentration factors

1. What are stress-concentration factors?

Stress-concentration factors (Kt) are numerical values that represent the ratio of the maximum stress at a point to the average stress over the entire cross-section of a structural component. They are used to determine the likelihood of failure in a component due to stress concentration caused by factors such as geometry, material properties, and loading conditions.

2. How are stress-concentration factors calculated?

Stress-concentration factors are typically calculated using analytical methods or numerical simulations, such as finite element analysis. These methods involve solving equations that take into account the geometry, material properties, and loading conditions of the component to determine the stress-concentration factor at a specific point.

3. What causes stress concentration in structural components?

Stress concentration in structural components can be caused by a variety of factors, including changes in geometry, sharp corners, holes, notches, and changes in material properties. These factors can lead to localized regions of high stress, which can significantly reduce the strength and durability of a component.

4. How do stress-concentration factors affect the design of structures?

Stress-concentration factors play a crucial role in the design of structures, as they can significantly affect the strength and durability of a component. Engineers must consider stress-concentration factors when designing components to ensure that they can withstand expected loads and avoid failure due to high stress concentrations.

5. Can stress-concentration factors be reduced or eliminated?

While stress-concentration factors cannot be entirely eliminated, they can be reduced through proper design and material selection. Techniques such as filleting, smoothing sharp corners, and using materials with higher ductility can help reduce the effects of stress concentration and improve the overall strength and durability of a component.
