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.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
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...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
