Re: [sympy] GSOC Singularity Function

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.

[sympy] GSOC Singularity Function

2018-02-13 Thread 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.

I recommend trying to solve beam bending or other problems that utilize
singularity functions with the current module. You will quickly find many
deficiencies and ideas for new features.

[sympy] GSoC : Singularity Function

2017-03-31 Thread satya prakash 
Hello,
   I would like to know reg. Singularity Function idea as there is already a 
package in function.special.
  So I am in confusion regarding what is needed to be done.
