    Interview questions for research engineer (orthopedic biomechanics)

    Hi all, There are lots of ideas and nice suggestions we can get from this forum to prepare for an interview but I could not find specifically about orthopedic biomechanics. It would be really helpful if anyone could share what kind of questions are asked to those applying for a research...

    Addition of extra vertebra and disc in a spine finite element model

    Hi, I have a research work on doing some biomechanical analysis on a spine finite element model. This spine model is from T1-S1 (first thoracic vertebra to Sacrum). But according to some data that I am provided with, I need to add an extra intervertebral disc and vertebra between two vertebrae...

    Quality Engineer in biomedical engineering

    Is it possible for a person with MS in bioengineering apply for quality engineering without any industrial experience? Are there specific courses that needs to be completed for this specific position? My previous post got deleted but I don't know why. I had posted the question just to gain some...

    Thermal expansion and material orientation

    Hi, I am trying to increase/decrease heights of vertebral body (local material orientation defined in z-axis )in a finite element scoliotic model using thermal expansion. The height is being changed but the problem is that it is not being changed according to the defined material orientation...

    Matlab code to make curvatures in finite element spine model

    Hello, I am sorry if I have posted this question in the wrong forum. I didn't know where to post it actually, therefore posting it here. I wanted to know if anyone has used Matlab code to make/change curves in the spine FE model. I have the code already and I do know where should I look at the...

    Confusion regarding element number

    Hi, I am currently trying to troubleshoot a model. The .dat file shows various errors in element number and when I tried to see the location for that particular element number, it is shown in two different parts in my model. What could have gone wrong that I see two different locations for a...

    Bone growth modeling

    I am trying to simulate bone growth in my spine model using a fortran code for the growth. If I use quadratic instead of linear elements in the hardware, will it result in convergence issues? Also, my next question is, whenever a maximum penetration error arises, is it because the contacts are...

    change in stress location

    A spine is instrumented with rods and screws and then simulated for a particular application. Why does the location of stress on rods change when varying the modulus of elasticity of the intervertebral disc of the spine?
