Assume that I'm going to investigate if jewelry pieces are strong enough under external loads. For example, consider a ring. I want to investigate if it can resist a punch force, or everyday forces like carrying a heavy suitcase while wearing the ring, or even sudden banging to a wall accidentally.
Is there any guideline or standard or code that helps me determine the direction and magnitude of the external loads on the jewelry pieces? Any documentation on that? Sorry if it sounds like a stupid question, I'm just trying to find a hint.
I'm specifically focusing on the gold metal and alloys of it.
