Thank you very much for your response. Yes, you're absolutly right, in slide 23 he uses the [B] vector to calculate the bending moment and shear forces by multiplying with the nodal deflectiones, but in thinking about your reply I realize that the [B] vector is essentially the same thing as the...
That's what I meant with the strain and stress fields, but what you propose is a good solution and not that more difficult to code. Thank you for your input.
I’m not an expert and FEA is not a primary aspect in the work I do (it’s a nice to have). But from what I know from university this is what I mean. In general terms, considering x as the normal direction from the beams section, what I mean by displacement field, is the ‘’elastic equation’’ (the...
I almost finished the matlab implementation of a particular 3d frame for multiple configuration scenarios,in matlab, as I stated on my previous post. I shall only check displacement criteria because I can't interpolate the strain and stress fields.
But I'm still curious about how to do this 3d...
Hello,
I have a question. I'm currently implementing a 3D spatial frame matlab FEM code based on Bernoulli beam. I'm building upon AJM Ferreira's book ''Matlab Codes for finite element Analysis'' formulations, because I want to automatize stress calculations on different configurations of a...
