Hello Group/Developers,
Recently we carried our elastic plastic analysis on torsional bar to find the residual stress. More details are available at https://youtu.be/Zw97RI4TgYM 14.
The simulation was further compared with Abaqus/Test results (reference) in a publicly available paper. While the results agreed nicely, it is observed that following improvement could make Calculix even better.
The contour plots are much smoother in reference, while in Calculix it appears bit patchy. Is it possible to improve on smoothness?. If there is any work around or something we missed any available methods, please direct us on the available options.
While we see it is possible to calculate the crack initiation life or fatigue safety factor, externally, native options can be very helpful. Can this be added as a feature? For example Dang Van criteria? We are aware crack propagation life can be calculated natively though.
Thanks for this great tool once again.
Best Regards,
CAE4U
P.S. This is a re-post on feature request from Calculix discourse as directed by community community members/user group
