Finite element (FE) optimizations... excuse me?

If you're wondering what FE optimizations are all about, here's a little insight 😎

The FE method can be used to virtually test components for strength. This is done using special computer programs and can lead to very different approaches depending on the objectives.

• The most common application is to simply check the safety of components that have already been designed.

• A more demanding application involves optimizing components geometrically so that they can withstand a specific load within a defined installation space. The notch effect usually has the greatest influence here, which is why it requires the utmost attention.

On the A30, not only the bolt and receiver have been optimized, but also small parts such as the bolt catch, the tension piece, and the trigger hanger.

These were optimizations aimed at increasing safety and resilience. To this end, highly stressed component areas were analyzed and geometrically optimized accordingly. Experienced designers can often use these optimizations to enable components to withstand twice as much stress.
