Finite Element Analysis (FEA) of 2D and 3D Truss Structure using MATLAB

Hello, this video briefs about how to use the MATLAB code to solve any truss structure. Also, the code displays Plots to visualize the displacement and stress on different elements.

I am working on a lattice element method, by which the continuum body can be analyzed as truss/spring elements. I find this video quite useful to construct my code for the 3D elements, especially the stress post-processing. Nice work!

Hi, could you please explain the use of the D_SETTINGS script. What exactly does it do in the FEM process of the code?

[austineadah]

This is so nice.could you extend it to choosing element types and sizes like in real applications?

No wonder you have such a good 386 (what) suscribers. What an I?

When I am following the same steps as you do, I get "unable to perform assignment because the size of the left side is 2-by-1 and the size of the right side is 3-by-1" error at the step "enter 0 if x or y is constrained 1 if not, on node in [bx;by]. The error is in line 37 of BOUNDARY CONDITIONS. How can I solve this?

What analytical method is used to write this code? Can you please provide some links related to it? Thanks

hello I am unable to open the script that you are using. could you upload it again?

I was just curious how I would go about changing the units to imperial on your plot and in the code? The example you gave is in my book, but it's in imperial units. Even when I tried converting the units manually I got a slightly different answer.

Can you share the matlab script file? The one in the description is .mat file and it does not allow to edit the code.

I have a problem.... Could you help me?

Sir can we apply finite element method for complex trusses like scissor truss of 8 members and other trusses of more than 10 members. If we can apply then, how we will calculate the angles if there are no horizontal members in the truss? Kindly suggest any book if you can, for the application of FEM for complex trusses

i can't open the file of the example in google drive its says unsupported
