Finite Element Analysis (FEA) is a powerful tool for evaluating complex structural problems. Like all analytical software, bad results stem from bad input. We call it the "Garbage in, Garbage Out" principle of FEA. Sometimes, with perfect inputs, you can still get the wrong answer using FEA. There are a lot of ways that your finite element analysis can take a wrong turn. So how do you know if your results are correct? The answer is validation and verification (V&V). This week we'll apply V&V to a simple beam bending problem.

The amount of time and effort that goes into making sure that nuclear plants safe is incredible. In the early 80s, Sandia National Labs (SNL) and Argonne National Labs (ANL) started a testing program for testing Reactor Containments. The pinnacle of the series of tests was the 1/4 scale model of a typical PWR Containment
FEA Drop Tests Today, more and more manufacturers are switching to analytical drop tests before anything goes into production. This helps save time and money, getting your products to market faster, but there’s more than just saving time and money, FEA offers some benefits that drop testing simply can’t do.
We can perform impact analyses in lieu of drop tests to verify structural integrity. This is an example of a dropped shipping container.
We thought it’d be fun to showcase some of our tools using a new series we call Crash Test Tuesday. This week, we’re going to start with a simple car crash. Who do you think would win in this crash – Geo Metro vs. 3/4 Ton pickup truck.
Failures Happen, Learn from Them If you’ve made it here, something probably went wrong. And you don’t want it to happen again. Failure is sometimes inevitable. All we can do is learn from it and fix the issues so it doesn’t happen again. But how do you know what to […]
A nuclear plant found that they needed to protect pipes from wind driven missiles. We designed a barrier system for them using 3D modeling and FEA.
Using FEA and hand calculations, we were able to help a nuclear utility evaluate RCP Seal Leakoff pipes and components for high temperature and pressure.
Tornado generated missiles can wreak havoc, especially on a nuclear power plant. We helped one site design and optimize a protection system.
Our CFD and FEA Consultants Experience At XCEED, our FEA consultants have over 20 years of experience using solving some of the toughest problems in the world. We started using FEA in the nuclear industry, pioneering it’s use as a cost savings tool. On one project alone, we saved $8.8M […]
