Hello everyone,

I am trying to model the SSI in 2D plane strain. When I am modelling the soil+footing exclusively, there is no problem.

However, when I want to introduce a pier [beam element] with a lumped mass on top of it, I cannot get the constraints right.

The soil is a deformable 2D plane strain body, the footing is declared as rigid body with a RP in the middle. The pier is a beam element whilst the lumped mass is a simple mass element [inertia/mass].

Dear Subscribers

I am a new abacus user and I am trying to simulate the interaction between two

the surfaces of 2 different parts and materials. Does anybody knows how can I proceed

in this simulation procedure. With pleasure any answer will be helpful from my work.

Thank you in advance

How can I use acoustic or ALE model in Abaqus?

Remarks on UMAT for plane stress problem

Submitted by Pu Zhang on Fri, 04/15/2016 - 18:26

software

There are a lot of sample UMAT subroutines for plane strain or 3D problems. However, it is difficult to find an example for the plane stress problem online. Even the UMAT manual does not provide enough information. I have tried the UMAT subroutine for the plane stress problem for a while. The following remarks may be useful for collegues who have interest.

1. The stress components σ₁₁, σ₂₂, σ₁₂ should be returned to UMAT. The other three stress components equal to zero, known as the basic assumption of the plane stress problem.

how can i model a BRB Brace in abaqus

hi every body

I model a brb(Buckling restrained brace) in Abaqus but my question is How to put concrete in a brb or How do I define the concrete inside the brb that work together? i use tie constraint But there isn't any stress for concrete!
i use static,General for analysis! is it correct?
