I am trying to solve 3 simultaneous equilibrium equations with the help of Mathematica. I have strain-displacement relations along with stress-strain relationships in cylindrical polar coordinates. The following images show the equations with which I am dealing with.
Hence putting stress-strain and strain-displacement into the equilibrium equations, we get 3 unknowns viz, ur, utheta and u_z (which are displacements).
Please help me here how can I solve these equations.
Also, please have a look at my notebook so that you will get clear idea.
