Homework Help: Solving for tensile test(materials) in FEM software

  1. May 21, 2012 #1
    1. The problem statement, all variables and given/known data
    I have to solve for the stress-strain curve of a tensile test(materials science) given the following data:

    d0 = 10 [mm]; d=9.925[mm] (average after d1' and d1'') and L0 = 100[mm];

    I have already solved the problem and charted the diagrams. But I would be most grateful if someone would be able to assist me in producing the numeric simulation.

    I am using Comsol 4.2 and the solid mechanics module. I've simplified the 3d model to a single cylinder of diameter 10[mm] and length of 100[mm]. I am applying a force of 11.39[kN] to both ends but the solver fails to complete and if I change some properties then it completes but the deformation does not show.

    3. The attempt at a solution
    It seems that I am unable to link images at the moment. If someone is interested I would be ok with messaging them links to the gui screenshots and my results.
