It's really great job , may Allah bless you Dr. Your explaining in details and so clear, making this part of structural dynamics easy to study. Thanks alot I have understand some parts of it difficult to get the ideas behinds.
thank you for all your explanations so far Dr. Dr. i'm curious about one thing in this impulsive loading topic, since every load has its own frequency (w.bar) including impulsive loading, is resonance going to happen if an impulsive loading applied at a strucutre which the natural frequency (w.n) equals to w.bar? even in short time td? because i didn't see w.bar variable in all formula in this impulsive loading topic,
thank you Dr. for your valuable effort at minute 25:55 , Is the function of the forced part correct ? I think that the denominator of the small triangle is Taw not (td)
@@dr.mohamednoureldin5718 Allah may bless you , I need any notes about how to read and understand the dynamic graphs such like (displacement-time) and (Acceleration-time) curves , but in your method especially because you are explain in detailes
Dear Dr. Mohamd, Thank you for your effort. Could you please help me to solve an problem ? It is : Duhamel integral method is used to calculate the half cycle of undamped SDOF structure For the displacement time history under the action of sine pulse, the structure is in a static state at the initial moment, and the pulse time history is p(t)=p0 sin w t 0 =< t bi/w need to calculate the time history displacement

Great work and learn alot of stuff
I also starts my channel and first course will be concrete technology, I need your support

Thanks, Mohamed. I will add a comment in the description regarding this.

Great work. Dr. I agree the damping and stiffness effect can be ignored when t
