  • MCalibration on Raspberry Pi

    MCalibration on Raspberry Pi

    Raspberry Pi is a credit-card-sized fully functional mini computer (available for about $35) running Linux. I have created a version of MCalibration , the most advanced material model calibration software that is currently available, that runs great on the Raspberry Pi computer. You can download the MCalibration application here....

  • FEA of PLLA Interference Screws

    FEA of PLLA Interference Screws

    I gave a presentation on advanced FE modeling of PLLA intereference screws at the ANSYS User's conference in Boston on Sep 14, 2011. In my presentation I discussed how the design of degradable screws can be optimized for use in Anterior cruciate ligament (ACL) reconstruction surgery. PLLA is a non-linear viscoplastic material that can be accurately modeled using the PolyUMod library.

  • ANSYS Conference in Boston

    ANSYS Conference in Boston

    I recently gave a presentation with the title Advanced User-Material Modeling of Cather Kinking at the ANSYS Regional Conferences in Boston on Oct 15, 2010. In this presentation I discussed some of my recent ANSYS simulation work (using UserMat subroutines) related to geometric instabilities of catheters. Like Abaqus, ANSYS supports the use a advanced user-material models and the PolyUMod library is now available for both Abaqus and ANSYS.

  • Bergstrom Simulia Conference 2010

    Bergstrom Simulia Conference 2010

    In May 2010, I gave a presentation at the Simulia User's Conference in Providence, RI. My talk had the title: "Finite Element Modeling of Thermoplastics at Different Materials". This is an area in which I have extensive experience, and it is an topic that a lot of people have problems with. In my presentation I used non-linear viscoelastic experimental data for a Polycarbonate (Lexan from SABIC Innovative Plastics). I then demonstrated that standard metal plasticity with rate dependence: ...

  • Three Network Model for Thermoplastics

    Three Network Model for Thermoplastics

    I have developed a new advanced thermomechanical constitutive model for thermoplastic materials. In the new model the micostructure of the material is represented using three distinct structural domains that capture the experimentally observed non-linear, time- and temperature-dependent response at both small and large strains. The attached paper presents the theory for the model, and the model calibration and validation are exemplified by direct comparison with experimental data for UHMWPE. Downl...

  • Material Modeling of Bread Dough

    Material Modeling of Bread Dough

    Bread dough is quite an interesting material with many similarities in its mechanical response to a lightly crosslinked elastomer. That is perhaps not too surprising since bread dough contains a network of gluten molecules. I recently published a paper on how to accurately model the response of this interesting material using an anisotropic version of the Bergstrom-Boyce model with Mullins damage. The model that we developed has been shown to accurately capture the non-linear viscoplastic response...

  • Updated PolymerFEM website

    Updated PolymerFEM website

    As you can see, I just updated the PolymerFEM.com website to a new style. It will likely take me a few days to update everything again, but the Forums page is still active

    Feel free to check it out.

  • Bergstrom-Boyce Model Info

    Bergstrom-Boyce Model Info

    If you are interested in learning more about the Bergstrom-Boyce (BB) model,
    which is now a built-in feature of both Abaqus and ANSYS, then you should consider checking out the Bergstrom-Boyce model page on PolymerMechanics.com, or the MCalibration software. The Bergstrom-Boyce model is a very accurate material model that can accurately predict the strain-rate dependence and hysteresis or elastomer-like materials. It is a model that I developed as part of my Ph.D. work at M.I.T. T...

  • Windows 7 & Abaqus

    Windows 7 & Abaqus

    The new Windows OS - Windows 7 - is scheduled to be released this fall. I have been trying out the release candidate of Windows 7 that is available and I am happy to let all Abaqus users know that Abaqus V6.9-1 works just fine on Windows 7. There is one trick that you may need to use, however, to install Abaqus on Windows 7. If you try to install the software just from the DVD then you might run into the problem that I did, i.e. the Abaqus installation program complained that I was trying to i...

  • Abaqus on Ubuntu Linux

    Abaqus on Ubuntu Linux

    I happy to announce that both Abaqus 6.9 and 6.10 work fine also on the two latest versions of Ubuntu Linux (9.10 and 10.4). I performed the same steps as listed in the following thread to install the Abaqus software.

    The new version of Ubuntu does not come with libstdc++5, but instead the newer libstdc++6. To make the software work I had to download and install the libstdc++5 library from the following debian page.
