Explicit FEA software is a powerful tool to model dynamic structures and transient loading. They are, time-consuming and difficult to troubleshoot. Often, FEA engineers apply simplifications to reduce model size computational expense. It’s essential that these simplifications applied to produce accurate results. A common error is reducing the model […]

Explosive hazards are prevalent in many industries. The source of these explosions can be accidental or malevolent. Regardless, site personnel need protection from these hazards. Blast-resistant buildings shield workers and critical assets from blast effects. In this post, we highlight Finite Element Analysis, and its application in the design of Blast Resistant Buildings. In this post we'll cover: Basic blast loading design concepts, differences between hand calculations and FEA, and blast analysis using FEA
Evaluating Tornado Missiles for RIS 2015-06? We’re going to help make it a little more intuitive. Tornado strikes might not be as bad as you once thought.
Most structures and their loads are symmetric. In these cases it's possible to take advantage of symmetry to simplify your Finite Element Analysis and reduce run time. In this blog we'll: Discuss benefits of using symmetry in FEA, provide a primer in symmetry theory, and Work through a FEA case study using symmetry.
In last week's blog, we discussed the science behind bolted connections. Specifically their response when subjected to a combined external load and preload. In this blog we'll work through the application of bolted joint science in a finite element analysis. We will: Provide an introduction to FEA modeling of pre-loaded bolted joints, discuss some common troubleshooting techniques, establish methods to validate results of the FEA model and highlight differences between bolted joint science and real-world application.
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 […]
We found that API-650 tanks are more robust than most expect. The water in this tank absorbed 30% of the energy of a truck going 93 mph!
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.
