Impulse study on the screw

Question asked by Yin Cheng Tiew on Aug 26, 2018

Hi. I am trying to do simulation to determine how the impulsive force will affect the strength of screw and the bracket.

I would like to simulate a constant force of 118N acted over different period of time (let's say 2s, 1s and 0.5s respectively) and what will be the impulsive reaction on the screw and bracket (the bracket or the screw will be subjected to failure first). May I know which type of simulation shall I use to simulate the case? Dynamic or linear? If for dynamic, how to determine the damping ratio of the material (material of mild steel for both screw and bracket).
