Strength of material knowlege base requirements
I'm a Mechanical Designer, who's been in the field for a considerable time. For the most part when material stresses where concern, engineers within the organization would take on this responsibility. As a result, I never really have acquire full exposure of this knowledge. You could say I have a basic understanding of the force to stress to strain relationship. I'm of course acquiring this knowledge on my own by referring to different medias (Machinery Handbook, engineering books & texts, online resources etc.), but there is considerable information to cover. I at least would like to acquire a knowledge base to determine stress loads, whether static or dynamic, but since there is so much information available, I don't if I'll be reviewing more than I require.
My questions:
What would be the requirements to acquire this knowledge base?
Where can I find good text or resources to acquire this knowledge base?
Is it a good idea to take some college courses and what would they be?
I thank you for any assistance you can provide.
Thank you,
