Failure Mechanics—Part II: The Central and Decisive Role
of Graphene in Defining the Elastic and Failure Properties
for all Isotropic Materials
Continuing from Part I (Christensen, 2014, “Failure Mechanics—Part I: The Coordination
Between Elasticity Theory and Failure Theory for all Isotropic Materials,” ASME J.
Appl. Mech., 81(8), p. 081001), the relationship between elastic energy and failure specification
is further developed. Part I established the coordination of failure theory with
Advanced Materials and Multifunctional Structures (AMMS) Group at Masdar Institute (MI) is seeking suitably qualified candidates for PhD/Postdoctoral positions. Please see attached document for details
Another couple of interesting articles to share. Using some "mechanics" principles, researchers have reasoned that 100,000 years ago, kangaroos were too heavy to hop.
A while ago, a different group of researchers published the results of computer modelling (using genetic algorithms) that showed dinosaurs might have hopped and skipped as forms of locomotion! (But only if particularly happy?)
These articles might be good to share with undergraduate engineers for discussion in tutorials. There are issues to discuss with assumptions in both cases.
I thought the following article might be of interest to some on this site.
Hello, colleagues!
Could anybody help me with the problem? How to convert nanoindentation data (force - penetration depth) into stress-strain curves? Is there any method that allows to make such a conversion if Berkovich indenter was used?
Thank You!
Best regards,

Experiment.com is a crowdfunding site for research (a Kickstarter for science!).
Open to all, a target amount for a project is set, and funds are raised through small individual donations. The success is based on how many people like your idea. It's kind of a fun/alternative idea to traditional grant sources! If you have an interesting idea, I recommend it.
