Matlab Modeling and FEM Simulation of Axisymmetric Stress-Strain

Continuing on the previous post on axisymmetric modeling in FEATool, we will here take a look at how to model axisymmetric stress-strain from structural mechanics by entering and parsing the governing equations directly into FEATool using Matlab m-file scripting. The problem we will be looking at is a hollow sphere …
