AI Thread Summary
The discussion focuses on the differences between Timoshenko and Euler-Bernoulli beam theories in vibration analysis. The Timoshenko beam model accounts for shear deformation, making it suitable for short or thick beams, while the Euler-Bernoulli model is simpler and typically used for slender beams. Users are advised to choose the Euler-Bernoulli model for most steel beams due to their slender nature, reserving Timoshenko for applications involving concrete beams. The conversation highlights the importance of selecting the appropriate model based on beam geometry and material properties. Understanding these distinctions is crucial for accurate dynamic and static analysis in engineering applications.

Hello,

I am looking for explanations and detailed studies or even brief ones about the differences in Vibration analysis and dynamic studies as well as static analysis between

Timoskenko beam and .Euler-bernoulli beam

when should i use Euler-bernoulli beam?

Thanks

Hi.As far as I know Timoshenko beam model includes the effect of shear efforts which is usually neglected when dealing with slender beams. The most of the beams you will encounter are slender (steel beams for example), which are much longer than wide so unless you're analyzing concrete beams (which are usually not so slender) I think you can use the Euler-Bernoulli beam,it's simpler.

Regards.

Michujo.
 
I already told you the difference in another thread, why create another thread and ask again?
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
