SUMMARY

The discussion focuses on the differences between Timoshenko beam and Euler-Bernoulli beam models in vibration analysis and dynamic studies. The Timoshenko beam model accounts for shear deformation, making it suitable for short and thick beams, while the Euler-Bernoulli beam model is applicable for slender beams where shear effects can be neglected. Users are advised to utilize the Euler-Bernoulli beam model for slender steel beams and the Timoshenko model for concrete beams, which are typically not slender. The conversation highlights the importance of selecting the appropriate model based on beam geometry.

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?
