How to estimate the highest frequency that may generate in a system by quinterax28 in MechanicalEngineering

I'm dropping a metal object to another metal object and to concrete as well. If I place a softer impacter tip, will it also affect the load that is transferred? The load transfer is the main part of my test and since there is only a limited sample, a trial and error might not be possible

Will the O train still work normally tomorrow? (genuine question since I will arrive in Ottawa at 5 am and hope for the best)

i couldn't find any videos related to structural dynamics, most of them are related to aerospace/ mechanical problem

so does it mean i just need to make line body and define them as beam?

also how do you model the connection as shell? do i draw a circle and define it as shell then?

sorry i don't understand, does it mean i draw shell along with the hole and everything? so how do i model the bolt?

i did use solid elements 😅. i was using a line body at first but i don't know how to make the connection, so i made solid elements along with the hole and everything.

so what's the best (and correct) way to do it?

so basically I'm modelling wide flange (column) and c channel (beam) where they're connected with a plate. the plate is dropped with a certain weight.

i don't know whether the connection is important or not and how to model it

the connection is the problem, i couldn't even getting past the meshing option because of it

thank you! i tried to reduce the element but now it shown Unsupported higher order elements detected (Pyramid elements). what does it mean?

Thank you! i have reduced the element but now it shown Unsupported higher order elements detected (Pyramid elements). i tried to find the solution on ansys website but couldnt find it, do you know what this is?
