General Shell Section (Abaqus)
Forums
Hello,
I have defined general shell section properties in my model in Abaqus. When I run the simulation, there's no stress out put data available. What could be the reason for this?
iMechanica Video: Why spaghetti never snaps in half? 130,000 fps slow mo video reveals
Challenge yourself to snap a spaghetti stick in half by bending two ends. It always snaps into three or more pieces, but not two. But why? Indeed this phenomenon has puzzled many people, including the great Richard Feynman, for many years. The puzzle was only solved in recent years. Slow mo videos by ultrahigh speed camera reveal why. Check out this iMechanica Video with 6+ million view on YouTube.
Generalised boundary conditions for hydrogen transport at crack tips
Dear iMechanicians,
I hope the present work is of interest to you. We present a new formulation for resolving the electrochemical-diffusion interface in hydrogen embrittlement modelling

Introducing iMechanica Video
If a picture is worth of 1,000 words, a 1-min video is worth of 1.8 million words. 1,000 word/frame x 30 frame/s x 60 s.
LOL, seriously? Maybe not. But a well made video does provide information in an effective and efficient way that is often times impossible via other media.
