GSOC Singularity Function

[tsenguun tsogbadrakh]

Hello 

My name is Tsenguun, and I'm doing my Masters degree in Computer Science currently, and I already have a BS and MS in Structural Engineering.

I wish to contribute to the singularity function of sumpy, and I have some other functionalities to propose.

In 2016, sampadsaha metioned the following:

Additional features if extra time (in new PR):

• Plot the shear, bending, slope and deflection diagrams.
• See if this works with the units package in the physics package.
• Compute the strain and stress at any location in the beam.

https://github.com/sympy/sympy/pull/11374

The calculation of beam's shear, moment, rotation, deflection diagram is really interesting for me and I have many experience, since I've taken many classes toward Finite Elements and Structural Analysis. 

I've written a python code to do all these and was trying to make a PyQt software of beam problems. Essentially the program I was working on simulates the following webpage: https://skyciv.com/free-beam-calculator/

If the library would support this, it would be great tool. Note that there can be many loads and they can be uniformly distributed, trapezoidal, point loads, and even hinges. 

Also, a very interesting thing to implement would be the following: http://www-classes.usc.edu/engr/ce/457/moment_table.pdf

Essentially we have predefined commonly used beams that is already being solved mathematically accurate. 

Given a cross section, stress, and strain calculation of any point would be good thing using finite element analysis or just plain old structural analysis.

Please me know how do I get started on this and see if my ideas are worth implementing, or it has already been implemented.

Also, I've created reinforced concrete moment capacity calculating app. You can check it out at beam.tsenguun.com We could also do non-linear analysis on this one. Currently, its following the ACI standard that is linear function.

Thank you.

Tsengunn,

This all sounds good. There is plenty to do to improve the continuum_mechanics package in sympy. I suggest trying to solve a variety of problems with the existing code and you will discover many areas for improvement.

Very nice work on your calculator!

I'm not sure we would want to go the route of the moment table, as the whole of SymPy is to do the calculations for arbitrary math needs. But you can use the moment table as unit tests for you code. If SymPy can't solve one of those, then there is a deficiency.
