Buckling in Rings
From oil drums to--yes--soda cans, liquid-filled cylindrical shells are everywhere. And, it turns out, these structures fail differently than empty shells or ones filled with a solid. Liquid-filled cylinders buckle in sequential rings. (Video, image, and research credit: S. Jain et al.; via Ars Technica)
i'm trudging through the ninth level of hell (teaching myself introductory solid mechanics because my PhD advisor told me to take advanced solid mechanics and I don't understand anything). pls help
Structural Analysis of a Wrench with ANSYS Discovery Live free download here http://fetchcfd.com/view-project/849
currently studying Solid Mechnics. I have decided to start revision early this year. A little more than a month till final exams. Let’s do this!!

Fluids Can Fracture
Fracture is a sudden, brittle breaking-apart that we generally associate with solid materials that get stressed too far. Some viscoelastic, non-Newtonian fluids have been known to fracture, but that was generally thought to be unusual. But a recent study turns that idea on its head, revealing that even simple, albeit highly viscous, liquids can fracture. (Image, video, and research credit: T. Lima et al.; via Gizmodo)
Breaking a Dam to Save It
The concrete that makes up so much of our world is usually local in origin. To keep costs low, engineers use locally-sourced ingredients to make it. But not all ingredients perform the same. (Video and image credit: Practical Engineering)
Ultra-Soft Solids Flow By Turning Inside Out
Can a solid flow? What would that even look like? Researchers explored these questions with an ultra-soft gel (think 100,000 times softer than a gummy bear) pumped through a ring-shaped annular pipe. (Image and research credit: J. Hwang et al.; via APS News) Read the full article
Chaotic Hose Instability
Steve Mould is back with another video looking at wild fluid behaviors. This time he's considering hose instabilities like the one that makes a water-carrying hose beyond a certain length to whip wildly back and forth. (Video and image credit: S. Mould) Read the full article
