Evading the strength-ductility trade-off dilemma in steel through gradient hierarchical nanotwins
It is a long-standing goal in metallurgy to enhance the strength of materials without sacrificing ductility. In a recent article in Nature Communications, we reported an effective way to evade the strength-ductility trade-off dilemma in twin-induced plasticity steel.
The Renaissance of Continuum Mechanics
Dear friends of IMechanica:
Primary data mining through Web of Science
reveals that the number of papers containing “continuum mechanics ” increases
rapidly these years. This is a very exciting fact to our mechanicians. Thus, I
wrote a short paper titled “The Renaissance of Continuum Mechanics”, which was just
published online via:

Rolling Ball
Hi,
Please refer to the figure given below. I want model this problem using ABAQUS.
Abaqus Max Principal vs Max Principal (Abs) values
Hi every one,
Does Any one know the difference between Max. Principal values and Max.Principal(Abs) values in Abaqus ? I searched from there manual..but they have not mentioned in there manual too..could you please let me know the difference between those two parameters? Thank you very much.

Prof. Markus Buehler from MIT will receive the 2014 Journal of Applied Mechanics Award for his paper "Bioinspired graphene nanogut" (Journal of Applied Mechanics, v 80, article 061009, 2013). Profs. Katia Bertoldi from Harvard University and Oscar Lopez-Pamies from University of Illinois will also receive the 2014 Journal of Applied Mechanics Award for their paper "Some remarks on the effect of interphases on the mechanical response and stability of fiber-reinforced elastomers" (Journal of Applied Mechanics, v 79, article 031023, 2012).
Question about Smeared Crack models
Hi, I want to ask you guys about how to model an unconfined conrete material with smeared crack model in abaqus 6.10, especially about what kind of parameter should I use and how much the value of parameter. I would really appreciate if you could give me some tutorial, explanation, or even an example of how should I model a smeared crack model in abaqus.
Thanks.
