Title: harmonic loading
Post by: JOYE on June 07, 2021, 07:17:13 AM
Hello sir, please suggest to me how to apply harmonic loading.
I have the frequency of 5 Hertz of 'to' and 'fro' movement for 100 sec.
In the manual according to my understanding prop. loading type-4 is I think fit for my problem.
but Initially, you suggested me like this (1 1 0 tm 0 0 am fq 0), tm=max.time, am=amplitude , fq=frequency
it's not completely clear to me how to implement it.
It would be great if you explain with an example.

Second, please suggest to me how to use csurf or cforce for applying normal loads on a rectangular block.

Thank you in advance!!!

Do you want to do this from the macro prompt during an interactive run or are you interested in doing this during a batch run?

Here is a simple bar problem that does your analysis.
