    Question about history output

    Hello, I have a question about energy history output. Short description of the mechanical problem: 1) Static analysis; 2) Pipe31H elements; 3) Elastic-Perfectly plastic material (no UMAT, just two point *PLASTIC definition) 4) Pipeline is laying on a flat surface (+friction interaction); 5)...

    Strange low convergence of axisymmetric problem

    Hello everyone. I wanted to make a very simple simulation - compression of cylindrical specimen. I was very surprised, when the solution was not converging.. and it is when more complex models work quiet well. It is a second day, but still I didn't found completely the reason of this strange...

    Meshing and tie constraints of RVE with inclusions

    Hello everybody, I came here to share my experience and get some view from a side: maybe someone give good idea, suggestion will see my mistakes. So, I am simulating compression of RVE: hyperelastic matrix (cube 70x70x70 mm with holes for inclusions) filled with spherical rigid (compared to...

    Mesh-to-mesh solution mapping via python script

    Hello everyone. I have a question concerning "Mesh-to-mesh solution mapping". In the Abaqus manual it is clearly explained how to do remeshing, using "Mesh-to-mesh solution mapping". There are even two examples can be found. However, all examples are based on using of .inp files. The only thing...

    Mystical contact problem

    Hello everyone! I am doing a nonlinear simulation of a compression test of a 2D geometry with round inclusions. Matrix is modeled as hyperelastic material, material of inclusions is chosen to be a lot stiffer then matrix. Geometry is compressed between two analytical rigid horizontal lines...

    Hyperelastic curve fitting. Ask for advices

    Hi, everyone Currently I am working with rubber, trying to get characterize its behaviour during compression and implement this information to FEM software (ANSYS in my case). So, I made a series of compression tests with[/sup] cylindrical samples and two types of boundary conditions: one...
