B1 - Finite Element Analysis Training : Basic Stiffness, Lesson 1

[@Enterfea]

I love your approach to this topic - and the animation is awesome! I will definitely follow this series :)

Would just like to point out that stress here is expressed as P/A which usually implies pressure over area. Though, stress is defined as force over area. Could this 'P' actually mean potential rather than pressure?

[@TonyAbbeyFETraining]

Hi Shaun,
sometimes P is used as a label for force, as in this case. I think the context should make it clear, and the diagrams. Pressure over area would not make physical sense, as you mention. I will label P as a force more clearly next time.
For a discussion of mine on stress, see:

Definitely. Just poking for clarification (:
Great video and animations -- minimal and concise!

amazing work, really thank you however i didnt understand the proof of why k is equal to A.E/L

Newton is now Hooke
