Intro to Rock Mechanics 1: Stress and Strain

Stress, strain, and a few ways they are unique in the field of rock mechanics.

thank you so much for your tutorial, you are so amazing to explain concepts and formulas in a short time, and make them understandable to me, i felt really frustrated studying rock mechanics, and i am so lucky to find your youtube. Really helpful. Many thanks!

I´m revisiting this area, working on O&G, thanks for sharing this are putting light into the shades of some SPE papers. Thank you!!

what book do you recommend to reinforce?

This video explains stress and strain in rock mechanics, including fracture stress and strain. It discusses the challenges of dealing with discontinuities and fractures in rock masses and highlights the importance of designing around rock features for engineering purposes.

[00:00] This video introduces key ideas in rock mechanics, rooted in mechanics and materials strength, with a focus on stress and strain.
- Stress is force per unit area, not the same as pressure, and causes strain
- Rocks behave differently than man-made materials, deforming chaotically
- Rocks have a defined elasto-plastic region, with a yield stress similar to metals

[03:00] Understanding strain in rock mechanics
- Tests specimens in rock mechanics are usually cylinders
- Compression applied to the cylinder causes a stress, denoted as Sigma
- Compression also causes a change in length, denoted as Delta
- Epsilon is the change in length divided by the original length
- Epsilon is a unitless percentage representing the strain

[05:57] Understanding stress and strain is crucial in rock mechanics
- Engineering stress and strain produce clean stress-strain curves
- Compression is positive and tension is negative in rock mechanics
- Rock mechanics deals with in situ rock masses bearing weight
- Discontinuities, joints, and fractures impact rock strength and failure

And there, you are back after a long one not 😒😒

cool stuff bro, i dont wanna get stuck in a hole

i like your videos so match but if you make arbic translut that will be so good for me 😳
Thanks 💖
