dynamic stress simulation

is their a possibility to applay stress like dynamic i have a shaft that has a pully on it , its conectet on an old way 

not with a tight fit so it shrinks on it but it works wit a small cut in the shaft where its bolted with just a tiny metal plate.


at this place will be a stress concentration and i wanne see how the noth effect is when their is a dynamic load on it cause if i put a static load on it i know the shaft can handel it but i real life it has broken couple of times so this is what i want to investigate shaft.png

i hope you understand my question and help me  kind regards

Can you test the assembly in the Dynamic Simulation environment and output time-steps to FEA for Motion Loads Analysis?


I don't see any twisting forces on your shaft - how is the shaft used in an assembly?

on the shaft is a pully that guides a  chain but somtimes the  chain blocks and so the motor + reductor builds up tention until it releases . i asume that the worst place is when the pully is in that direction when the pulling force is in a perpendicular direction with the flat surface  so the shaft is getting "pulled open" if you get what i mean . i think multiple times of this force will tear the shaft at the red line in the picture. this is how i wanne simulated it 


can i do this with inventor or do i need the multi physics for it ? 


in other words their isnt going to be a twisting force cause the chain guides trough it only the friction between the chain and pully is going to make it turn around but this forces are neglecteble 


Kind regards
