有人告诉我他们曾经使用NRL拱来获得材料的mu和eps。
我从来没有听说过这个，从数学上不知道这样的事情怎么可能。
我或许可以认为来自s21的eps是可能的，但即使这样做也不是一件非常不切实际的事情。
有人知道NRL拱门请告诉我他们知道什么吗？

Someone told me they used to use an NRL arch to obtain mu and eps of a material. I've never heard of this and from the mathema
tics don't know how such a thing would be possible. I could perhaps consider it being possible for eps from the s21 but even that would not be a very impractical thing to do.
Could someone who knows about NRL arch please tell me what they know?
