Mastering the Global Stiffness Matrix for Planar Trusses: Tips and Resources

AI Thread Summary
Forming the Global Stiffness Matrix for planar trusses can be challenging, prompting a request for online resources. A recommended resource is "A First Course in the Finite Element Method" by Logan, which provides a clear explanation and worked examples of the plane truss problem. Additionally, Moaveni's book on finite element analysis includes examples relevant for using ANSYS, although it is noted to be less effective for learning. These texts are valuable for understanding the concepts and practical applications of FEA in truss analysis. Utilizing these resources can enhance comprehension and application of the Global Stiffness Matrix in planar trusses.

I am having trouble forming the Global Stiffness Matrix for a planar truss. Does anyone know of any good online resources to help me with this? I've found a few, but haven't been much help.

I don't know of any online sources, but the FEA class I'm taking uses a book called "A First Course in the Finite Element Method" by Logan. It contains an excellent description of the plane truss problem with worked examples.
 
I agree with Brian C...Logan's book is a superb introduction to FEA and has the plane truss problem.

If you want to use ANSYS to solve the problem, I believe Moaveni's book on the FEA has one or two examples. I used Moaveni's book for my FEA class and while it's not great to learn from, it's pretty decent as a walkthru for ANSYS.

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
