    Example on using stiffness matrices in Abaqus

    Hi all, I'm trying to use stiffness matrices to define material behaviour. I've never used this method before and I find the documentation from Abaqus quite confusing. I've tried to use *USER ELEMENT and *MATRIX, TYPE=STIFFNESS But I'm sure I've been using them wrong as I have no idea what...

    Surface offset issue

    Hi, I've been using SOLIDWORKS to work on a design created in CATIA. What I'm trying to do is to create several surface offsets from one side of the rod-like shape I have. That side I'm trying to offset is made up of three different surfaces. So, I knit the surfaces (using merge as well) and...

    Applying interference fit contact

    Hi, I'm trying to model a cuboid sandwiched between two less stiff blocks, as shown in the cross-sectional view below. This model is intended for some iterative analysis where the parts are expected to have an arbitrary level of initial overclosure. I applied a surface-to-surface, hard...

    Intradiscal pressure in ABAQUS

    Hi, I'm modelling and intact spinal segment under pure axial compression. In order to indirectly validate with results from literature I need to find the intradiscal pressure (hydrostatic pressure of the nucleus as I understand). The nucleus is defined as an incompressible isotropic...
