This topic was on my mind (and on my to-write list) for a very long time. Finally, I had the time to organize what I want to write about it in my head. I wonder what is your take on this matter - be sure to leave a comment below! What does it mean to [...]
I got a really interesting question on my email from Fateme. I wanted to address this issue so many times now, so finally there is a great occasion to do this! In Abaqus, can we review the capability of a structural member? Whether or not it can bear the load like: shear, bending, twisting, axial [...]
Last time I described 5 steps to FEA results verification. Among those steps were FEA results verification with hand calculations. I figured it makes sense to expand on this idea. Especially since Luke asked me about something on this topic via email. Luke asks: How is the eigenvalue calculated, can this be done longhand? Can [...]
Whatever we design life will verify it at the end... but I would rather know if my design has a fighting chance before any major collapse occurs! This is why FEA results verification is a very important thing. When you are solving a known problem (i.e. as a benchmark) this is easy to do. You [...]
If you are starting with nonlinear FEA you most likely heard the term load multiplier. Usually, people associate this with some sort of "safety factor" but frankly this has nothing to do with safety. In fact, this is the only way you can get an outcome out of nonlinear analysis and today I will explain [...]
When I first started working with Finite Element Analysis (FEA) I had a huge problem in understanding what to do. I had a basic engineering knowledge but I simply did not understand what was the order of the steps. Suddenly the software had many "modules" and each was screaming at me that some data is [...]
Designing steel silos with analytical approach always yields very conservative results. Nonlinear Finite Element Method allow for great optimization of those structures (and other shell structures as well!). I will discuss this based on a silo I have recently designed. […]
