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.
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

A well-made video of interview with Professor James R. Rice of Harvard University in 2019
This video records an invited talk by Teng Li presented at the 2019 US National Committee of Theoretical and Applied Mechanics annual meeting held at the National Academy Science Building in DC on March 29, 2019. The talk lasts ~35 min. Q&A session starts at 36'00", with some interesting discussions about iMechanica.

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.
The University of California Merced seeks applications for a postdoctoral scholar in the Martini Research Group. The position requires significant experience with atomistic simulations using empirical model-based simulation tools and strong computational skills in general, as well as excellent oral and written communication skills. Preference will be given to applicants whose research background includes investigation of the mechanical properties of nanoparticles. The position is for one year with the possibility of renewal.
For researchers and industrialists being active and/or interested in finite element modeling of machining operations and surface integrity:
Our group has recently published a study on micro-scale testing of short-term creep of cement paste using microcantilever testing. If you are interested, more details can be found at: https://www.researchgate.net/publication/341668724_Micro-cantilever_tes…;
