    Hi these are good questions, but I guess these are elementary. If you could indicate the experience level of the questions it may be very useful.
    Also are you planning to add answers ? Need any help ??

    and i want to some more questions for experienced persons.

    1) Why model analysis done at linear static condition?
    2) what wil happen if lagrange multiplier and MPC algorithms used to the surface to surface contact model?
    3) what is diff between the bilinear isotropic and kinematics hardnings?


    share your answers

    i will post answers soon.

    Examples of greater depths and technical superiority are essential for these interviews. More questions with case study could help a lot and would benefit everyone out there.
