J integral and Q parameter
Does anyone know how I can calculate J integral from descrete displacement field, stress and strain data which I estimated from experiment?

Update: Journal Club Entry July 2014: Overcoming Challenges in Liquid Crystalline Elastomers
Dear iMechanica,
Last July I posted a journal club entry on overcoming the traditional challenges in mechanically actuating liquid-crystalline elastomers (http://imechanica.org/node/16853). I'm glad to say we finally got our first manuscript regarding this work published in RSC Advances (DOI: 10.1039/C5RA01039J).

Abaqus tools
<p>Hi all</p>
<p>im modeling an laminated rubber isolator in abaqus and i have used mooney rivlin model.My model consists of three layers of rubber and steel plates in between. I dont know how to view the results for seperate parts of rubber and also how to adjust the contour plot valuees. kindly help me with it. thanks in advance.<a href="http://imechanica.org/comment/26854#comment-26854"><br /></a></p>
ageing viscoelastic
Hello everone
I am recently interested in viscoelastic composite materials with ageing effect. I will be very pleased if someone can advise me how to find a constitutive law with ageing effect.
sincerely

On the modeling of asymmetric yield functions
In the context of metal plasticity, the yield function of a metal polycrystal is its most complex macro-characteristic. Letting aside the questions of kinematic or distortional hardening, the basic problem is geometric in nature: to design a family of convex surfaces capable of reproducing a wide range of experimental, or theoretically predicted data. While many satisfactory solutions have been proposed for the modeling of symmetric (with respect to the origin of the stress space) yield functions, the more general case of asymmetric functions has not witnessed comparable progress.
Is energy conservation satisfied in the current deformation application schemes in molecular dynamic simulations?
In our recent paper, we examined the energy conservation for the current schemes of applying active deformation in molecular dynamics (MD) simulations. Specifically, two methods are examined. One is scaling the dimension of the simulation box and the atom positions via an affine transformation, suitable for the periodic system. The other is moving the rigid walls that interact with the atoms in the system, suitable for the non-periodic system.
