Who should attend
Dear friends
I'm modelling a large penetration of a strip footing in clay soil. I'm using a Python script (Abaqus 6.13) for this.
Hi Sirs,
As title, I wondering if the problem can be solved with only material residual stress but no other external load applied?
After several trials, Abaqus returns message
"MASS OR DIFFERENTIAL STIFFNESS MATRIX IS COMPLETELY NULL. THE EIGENPROBLEM CANNOT BE SOLVED. IN A *BUCKLE ANALYSIS THE MOST LIKELY CAUSE IS THAT A NONZERO LOADING PATTERN WAS NOT SPECIFIED VIA *BOUNDARY, *CLOAD, *DLOAD, ETC,. SEE Eigenvalue Buckling Prediction IN THE ABAQUS/STANDARD USERS MANUAL"
We're running a series of free workshops at the AMP Technology Centre in Rotherham (June 27th), the University of Liverpool (June 28th) and the University of Leeds (June 29th) this month, where we'll be explaining the benefits of Simpleware for working with 3D image data.
Dear Colleagues,
A brand new Siconos 4.0.0 is out !! Siconos is now distributed under Apache 2.0 license.
What is Siconos ?
Siconos is an open-source scientific software primarily targeted at modeling and simulating nonsmooth dynamical systems in C++ and in Python:
+ Mechanical systems (rigid or solid) with unilateral contact and Coulomb friction and impact (nonsmooth mechanics, contact dynamics, multibody systems dynamics or granular materials).
Dear iMechanica community,
you can find the UMAT-implementation of a Zener model, i.e. a Maxwell model parallel to a spring, in my PhD thesis:

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].
