    when would vertical strain equal negative of lateral strain?

    I am compressing a hyperelastic material in a 2D plane strain quasi-static model. When I view my strain results, my maximum principal logarithmic strain equals the negative of my minimum principal logarithmic strain. Not sure why this occurred since Poisson's ratio is assumed .5 not 1. Any...

    Max principal logarithmic strain equals negative min principal strain?

    Report XY Coord and Variable Output (i.e. Stress) for entire mesh

    Hello, Is there a way to display xy coordinates of undeformed mesh and the output variable for the entire part/mesh instead of selecting each node individually and writing to file using Tools->query. Thanks Richard

    environment file

    Hello, does anyone have an updated environment file I can take a look at that works for abaqus version 6.8. We ugraded from v6.7 and I get the following error when I try to run a program with my existing env file. Attached is my old env file. Any idea what I am missing? I get the error when i...

    Logarithmic Strain output in ABAQUS

    I am compressing a hyperelastic material in ABAQUS Standard. When I am visualizing my results I get a large negative logarithmic strain (< -1). How is it possible to have a strain smaller than -1 in compression (LE22)? Thanks Richard

    Low modulus linear elastic material convergence issues

    Hello, I am trying to run a 2D static contact analysis between a cylindrical rigid material and a flat low modulus linear elastic material (20 MPa) subjected to a fairly large force (2000 N). I have solved the excessive distorted element problems but am now having trouble with solution...

    help with adding MPC in keyword editor

    I am trying to use the Quadratic multipoint contraint in order to reduce the amount of elements in my model. So I am trying to go from a fine to a course mesh, but I am unsure of where to add this MPC constraint within the keyword editor. In the ABAQUS/Standard tutorial, for the cargo crane...
