Fea Engineer interview questions shared by candidates
When modeling rubber like material in explicit FEA, you can't set Poisson's ratio as 0.5. Why? What would happen in the solver if you do that? I noted that it leads to an infinity in the stiffness matrix but he wanted more details.
2 Answers↳
Velocity @n+1/2 and disp @n+1 after calculating accelerations at nth time
↳
How does explicit FEA solve governing equations? and what does this solve for? Told him that it solves for accelerations and then computes damping and displacement in next timesteps.... Less
How to improve the permanent displacement of the connector
1 Answers↳
lower the length of the pin and change to a harder material
Do you know vibration?
1 Answers↳
Yes, I took the course in my undergraduate education. But most of my experience is in aerospace static stress analysis. I'm assuming you would have a good documentation there for new starters in automotive. (they literally didn't have anything to study & etc.) Less
What properties determine the natural frequency of a simple system (a mass point on a spring), and which way?
1 Answers↳
Stiffness, which is related to the material and shape of the spring. The greater the stiffness, the higher the frequencies. Mass. The greater the mass, the lower the frequencies. Omega = sqrt(k/m). Less
