    Unrealistic high stress at a few elements

    Hi Mustaine, Thanks for the suggestions and help.

    Unrealistic high stress at a few elements

    Thanks for your suggestion I checked these and only some (+-10 nodes) are not included, but these nodes are located somewhere else, not at the stress-concentration location

    Unrealistic high stress at a few elements

    Hi Mustaine. I only defined a tie knot constrain at those nodes (the nodes from the cup are the slave nodes). I selected this for all the nodes that are on the outside of the cup, but the others do not show a problem.

    Unrealistic high stress at a few elements

    Hi StefCon, Thanks for your reply. I tried it but unfortunately the problem is still present. The stress decreased a bit, from 54 Mpa to 49 mpa.

    Unrealistic high stress at a few elements

    Hi Mustaine, Thank you for your reply and help. I use linear elastic homogenous material properties. I did not define plasticity because with this relatively low amount of force the materials should not plastically deform. At first i thought the cause for these high stress elements was because...

    Unrealistic high stress at a few elements

    Hi everyone, I am doing a FEM-analysis in Abaqus of a human hip with an implant. However, when I apply a static load of 2000N (which occurs during walking) I obtain a high stress (400 Mpa) for a few elements at the interface between bone and implant(see figure top left). The majority of the...
