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.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
