Hello. I am working on a project that investigates the stresses in severe scoliosis. Unfortunately, severe scoliosis has not been studied much using FEM. Can you help me to find the suitable Loading and Torque for the situation when the cobb angle is greater than 40 degrees? Or to Recommend me an article that has good information in this field.
Thank you so much for your attention and participation.
Dear colleague!
Perhaps it is a beam (spine) with a distributed load?
I would recommend trying the simplest mathematical models for FEM analysis. If they are approximately close, they can be further complicated.
A sideways curvature of the spine is scoliosis. In general, a curve is considered significant if it is greater than 25 to 30 degrees. Curves exceeding 45 to 50 degrees are considered severe and often require more aggressive treatment.
So try giving this as an Angular displacement load invoking the large displacement option. Also, use a suitable material model for the bone(s).
