SolidWorks FEA (Varying Cross Section)

AI Thread Summary
SolidWorks calculates stresses in FEA simulations using mathematical principles, including the second moment of area. Understanding the underlying mathematics of Finite Element Analysis (FEA) is crucial for accurate simulations. The discussion highlights the importance of grasping FEA concepts over traditional beam analysis for complex geometries. The user acknowledges that learning the math behind FEA is essential for effectively solving simulation problems. Overall, a solid foundation in FEA mathematics enhances the accuracy of stress calculations in SolidWorks.

Does anyone know how SolidWorks calculates the stresses for this simulation. Can anyone give me an idea, is it second moment of area? y/r = m/i?

Thanks
Richard.

Before we can answer this question, do you know how FEA works? (I mean the maths of it)
 
I'm halfway through a course on FEA at the moment, its becoming more obvious that using that mathematics will be the best way to solve the problem, rather than using beam analysis.
Sort of answered my own question.
Thanks anyway.
 
I mean how the FEA program uses maths to solve the problem? Or how FEA solves problems in general?
 

Thread 'Bubble formation in 4 mm gap vessel'

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 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...

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

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...
