truss example for 4 joints and 4 elements - preceptor - 11-22-2009 Advanced Example For Finite Element Analysis of Truss Example
about: Matlab code for 4 nods and 4 truss elements dear members this example developed for finite element analysis and you will see that include advanced method, im working on beam,frame etc.. it will be available soon......... regards urbana you can use freely m.file (there are a important thing that is a practice) Code: *************************************** Code: *************************************** Joint1 u=0 v=0 Joint2 u=-9.0016e-035 v=-0.0081852 Joint3 u=0.0026667 v=-0.0081852 Joint4 u=0 v=0 Member1 f1i=6.7512e-030 f1j=-6.7512e-030 Member2 f1i=-133.3333 f1j=133.3333 Member3 f1i=1.1369e-013 f1j=-1.1369e-013 Member4 f1i=166.6667 f1j=-166.6667 RE: truss example for 4 joints and 4 elements - elbarto_87 - 11-23-2009 Nice work urbana. I wrote a similar program in MATLAB last year to do 3d frame analysis using the dirrect stiffness method but after writing the program I realized how NOT TO write a program in MATLAB (I used global variables, should have looked more into an OOP approach) although it did work. If you are interested in continuing your development please let me know if I can make a contribution to anything as I would be willing to add where I can. I have a mfile I wrote for partitioning the stiffness matrix (also works on node loads etc) which was written using logical indexing so it will be much faster then looping if you are interested. I will try and upload it somewhere to share if you are interested. There is a lack of a good general frame analysis toolbox released under a BSD license for Matlab. I would be very interested to hear about the rest of your project. Regards Elbarto RE: truss example for 4 joints and 4 elements - preceptor - 11-23-2009 dear elbarto thanx your interest please please you can share please open the new thread note: if you follow the forum rules,i will grateful to you regards |
