Higher-order adaptive finite-element methods for Kohn-Sham density functional theory
Dear Colleagues,
I wish to share with you our recent article on "Higher-order adaptive finite-element method for Kohn-Sham density functional theory", which will soon appear in the Journal of Computational Physics. Below is the abstract and attached is a preprint of the article.

Saturated Soil Material Property in abaqus
Hello everyone,
I need an urgent help. I have no idea how to define two phase poroelastic soil in abaqus. Water and soil should be treated as two different materials rather than a single material. And how to define the poroelasticity (saturated soil). Can abaqus perform these analysis.
(1) Coupled quasi-static for saturated soil
(2) Coupled dynamic for saturated soil (the UEL/UMAT) -- this is
reported as a UMAT.
reported as a UMAT.
Please help me how to sdo these steps and how to define UEL/UMAT
Regards
Rahul

Overall Mechanical Response of Particle-Reinforced Elastomers at Finite Strains
[img_assist|nid=15079|title=Elastomers Reinforced by Spherical Particles Under Different Loading Conditions|desc=|link=none|align=left|width=300|height=264]Abstract An approximate homogenization method is proposed and used to obtain estimates for the effective constitutive behavior and associated microstructure evolution in hyperelastic composites undergoing finite-strain deformations.
Varying Yield Strength through depth in Abaqus
Hi,
I am trying to create a material model in Abaqus such that I have a varying yield strength through the depth (y-coordinate). I want a model which has maximum yield strength at the top surface and gradually goes on decreasing with y-coordinate. Is there a way to do this? Any help/insight would be greatly appreciated. Thank you.
Regards,

Hi,
I am working with a finite element code implemented in C++ in my research group. Recentl I implemneted an incompressible finite strain element.
Currently I am making use of verification tests to check whether my element runs accurately for various hyperelastic strain-energy models. I have succesfully completed a verification test using the Mooney-rivlin strain-energy density function. However, I have been unable to find verification/benchmark tests which I may use to test other strain-energy density functions.
