Hi

 I am working on the nonlinear inelastic analysis of concrete-filled steel tubular (CFST) short columns under axial loading. How do I use RIKS method availbale in ABAQUS? This method is used to apply load. How do I use load-control method in ABAQUS? How do I obtain load-strain curve for CFST column?

Best regards,

Vipul Patel

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

Poroelastic soil Material 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.
Please help me how to sdo these steps and how to define UEL/UMAT
Regards
Rahul
