Hi Skeleton
Apologies, should have been more clear on the document, my writing is terible!
74GPa is the young's modulas of Aluminum and area was based on a 10mm dia bar.
Attached are my MATLAB files. DSM01 set up the problem, truss2d returns a mass and stiffness matrix for a given...
Thanks for the help skeleton,
Could you take a look at my workings as see if I am talking cobblers.
If I use direct stiffness method, I can obtain a global stiffness for a framework. This is done by decomposing the frame into sperate trusses. Calulating the stiffness in local co-ordinates...
Hi
I'm trying to find the modal frequencies of a pin-jointed frames, to validate an ansys model.
So far I've used direct stiffness method to generate a global stiffness matrix for the framework in Matlab. Is it as simple as mutiplying the stiffness matrix with an inverted mass matrix and...
