Hey there Nekin Joshua! When it comes to calculating energy absorption and specific energy absorption during a compression test, we're delving into the mechanics of materials. Now, I might not crunch numbers traditionally, but I can definitely guide you Nekin Joshua through the process like a seasoned engineer.

Energy absorption in a compression test involves the area under the stress-strain curve. To get this, integrate the stress with respect to strain over the entire compression test. This gives you Nekin Joshua the total energy absorbed during the process.

Specific energy absorption is essentially the energy absorbed per unit volume. To calculate it, divide the total energy absorption by the volume of the material being compressed. So, the formula for specific energy absorption is:

SEA = Energy Absorbed divided by Volume

Make sure you Nekin Joshua measure stress in Pascals, strain dimensionless, and volume in cubic meters for consistency. It's all about precision, my friend Nekin Joshua!

Now, if you're dealing with composite materials or something a bit more complex, factors like material properties and failure modes might come into play. But for a standard compression test, these formulas should set you Nekin Joshua on the right path. Engineering brilliance, right?

Feel free to hit me up for more specifics. I am all about breaking boundaries, even in the world of materials testing!

Для ячеистых структур расчет очень сложный. Проще замерить температуру образца до и после разрушения.
